Shareware distribution gives users a chance to try software before buying it. If you try a shareware program and continue using it, you are expected to register. Individual programs differ on details -- some request registration while others require it, some specify a maximum trial period. With registration, you get anything from the simple right to continue using the software to an updated program with printed manual. Copyright laws apply to both shareware and commercial software, and the copyright holder retains all rights, with a few specific exceptions as stated below. Shareware authors are accomplished programmers, just like commercial authors, and the programs are of comparable quality. (In both cases, there are good programs and bad ones!) The main difference is in the method of distribution. The author specifically grants the right to copy and distribute the software, either to all and sundry or to a specific group. For example, some authors require written permission before a commercial disk vendor may copy their shareware. Shareware is a distribution method, not a type of software. You should find software that suits your needs and pocketbook, whether it's commercial or shareware. The shareware system makes fitting your needs easier, because you can try before you buy. And because the overhead is low, prices are low also. Shareware has the ultimate money-back guarantee -- if you don't use the product, you don't pay for it. CMFiler is a copyrighted shareware program by Charles F. Martin, President, NoVaSoft and author member of the Association of Shareware Professionals. The evaluation edition of CMFiler is offered at no charge to any potential user for evaluation. Feel free to share the evaluation edition with your friends, but please do not give it away altered or as part of another system. The essence of "user-supported" software is to provide personal computer users with quality software without high prices, and yet to provide incentive for programmers to continue to develop new products. _____ Ombudsman Statement. . . This program program is produced by a member of the Association of Shareware Professionals (ASP). ASP wants to make sure that the shareware principle works for you. If you are unable to resolve a shareware- related problem with an ASP member by contacting the member directly, ASP may be able to help. The ASP Ombudsman can help you resolve a dispute or problem with an ASP member, but does not provide technical support for members' products. Please write to the ASP Ombudsman at 545 Grover Road, Muskegon, MI 49442 or send a CompuServe message via CompuServe Mail to ASP Ombudsman 70007,3536. _____ CMFiler Disclaimer - Agreement. . . Users of CMFiler must accept this disclaimer of warranty: CMFiler is supplied as-is. The author disclaims all warranties, expressed or implied, including, without limitation, the warranties of merchantability and of fitness for any purpose. The author assumes no liability for damages, direct or consequential, which may result from the use of CMFiler.

There are ten files in the CMFiler package: o CMFILER.COM - The "kernel" of the CMFiler program o CMFILER.OVY - Its supporting program overlay o CMFILER.DOC - This manual, which is the full documentation o CMFILER.BRF - A brief summary of features for quick reference o CMFILER.REG - A file containing the registration form, an explanation of the shareware concept, and a statement of the Association of Shareware Professionals concerning its ombudsman services for registered users of shareware applications. o DESC2NAR.COM- A program for 4DOS/NDOS users for converting the DESCRIPT.ION files containing file and directory notes into the CMFiler NARATIVE.CF file format. o DESC2NAR.DOC- The documentation for DESC2NAR.COM. o CHANGES - A brief compilation of the changes and bug fixes since Version 5.22. o READ.ME - A file with installation instructions. o FILE_ID.DIZ - A description file used by BBS system operators. CMFiler is not "public domain" software or "freeware". It is offered as shareware for evaluation and distribution unaltered to others, with the understanding that, if you find you are using it after a 60-day trial period, you will pay a registration fee of $30. Please refer to CMFILER.REG for registration information and a definition of shareware. I am so convinced of CMFiler's wide usability and appeal that, once you register your copy, I will send you an instant $10 commission each and every time someone else registers a copy and cites you as the source of it! You may make as much money by passing CMFiler to others as you care to. CMFiler MUST be passed as an UNALTERED collection of the evaluation editions of the files CMFILER.COM/.OVY plus the other files listed above, together on one disk, or as a compressed file, e.g., using the PKZIP utility. The form in which I prefer to pass CMFiler, because it requires no external decompression utilities, is as the self-extracting file CMFILER.EXE, which on execution extracts all ten files. A perfectly suitable alternative form, preferable if you have the PKZIP utilities because it takes up less space, is as the ZIP file CMFILER.ZIP, which on unZIPping yields all ten files. Any package that contains all ten files unaltered is acceptable. CMFiler provides a quick, simple, "one-touch" operating environment for your IBM-compatible 80x86-based computer running under DOS Version 2 or later. While its name implies it is a file manager, it is much, MUCH more. Once you have used CMFiler for a few sessions, you will not want to struggle with the DOS COMMAND.COM command processor or your other file managers ever again! CMFiler was painstakingly written in Assembly language over a three-year period, carefully factoring in the suggestions of a dozen of the world's pickiest software critics. It is compact and lightning fast. CMFiler is capable of doing everything your DOS COMMAND.COM processor or other file manager can do, and more, but with EASE! -- displaying two directories side-by-side; copying one or more files from one directory to another; backing up files in the same directory; deleting and renaming files and directories; setting file and directory attributes; concatenating (stringing together) multiple files; viewing and editing files; making and removing subdirectories; printing files in the "background" while you perform other tasks; setting disk volume labels; printing directory listings; keeping notes; displaying two disk structures side-by-side as "trees", and performing a full set of operations on their structures; and executing child processes -- all with a minimum number of keystrokes and maximum "transparency". Operations are keyed to single-letter mnemonics, making CMFiler intuitive and easy to learn. For example, the letter C means "copy", the letter D "delete", and so forth. Almost everything you need to know about CMFiler is contained in a two-line prompt at the bottom of the screen, or can be summoned instantly with a single keystroke (surprise! H for "help"), with no delay for external file reading, since the help is imbedded in the program code. There are only a few things for which you will need to refer to this manual once you begin using CMFiler. CMFiler employs the BIOS and DOS disk service routines which are embedded in ROM or loaded into RAM when your computer boots, and the DOS file operation safeguards and error flags are employed, such as denying access to remove non-void subdirectories. I have added a few of my own, such as protection of files against being overwritten by zero-length files of the same name (resulting from an occasional DOS read-write failure). CMFiler performs most operations immediately, and does not ask for confirmation as other file managers do, unless file destruction is involved. You must confirm with a separate keystroke, for example, CMFiler -- Overview Ov-2 that you really DO want to delete files, or that you really DO want to overwrite a more recent version of a file during a copy operation. Otherwise CMFiler takes for granted that you are doing exactly what you had in mind, on the basis that a mistake can be recovered from with just a few more keystrokes. The "mass" operations, like copying large numbers of tagged files, all have an Esc bailout. _____ Program Logical and Physical Organization. . . The CMFiler program code is organized "logically" (in the programmer's sense) into three sections, or "modules". These will be referred to variously as the "main module" or "main screen"; the "editor module" or "editor"; and the "tree module" or "tree functions". Each module performs some major function or group of functions which is fundamentally different from the rest, discussed further below. On the other hand, the program is broken PHYSICALLY into two main pieces, in this case two files, namely, the file "CMFILER.COM", sometimes referred to herein as the "kernel"; and the file "CMFILER.OVY", or the "overlay". The kernel contains the most vital part of the main module, the "starter", and the overlay, which the kernel loads contiguous to itself in memory, contains the rest of the main module, plus all of the editor and tree modules. A memory map is included in this manual for those interested. The main module displays one directory on the left side of the screen, or two directories in side-by-side panels. The subdirectories of each directory are always shown at the top of the listing in alphabetical order, following by the files in one of seven user-specified ordering schemes. Commands operate on a subdirectory or one or more files in one panel (the source panel). Some commands, like Copy, write to the directory in the other panel (the target panel). The main module gives a somewhat myopic or "microscopic" view of your disk, one directory at a time, but does so with the most complete set of file and directory services available in the file manager today. The other two modules (editor and tree) are accessed from the main, and the editor may also be accessed from the tree. The editor is called to create, edit or view a file. To view or edit an existing file in the main module, just put the cursor on it and press E or Enter. To create a file, press F and type in a name for the new file. The tree module is called from the main module with Shift-T. It displays the entire directory tree structure of one disk in the left panel, or two trees for the same or different disks in side-by-side panels. Whole structures ("branches") of a tree, or if you wish just the files in one directory, may be copied, moved or deleted in their entirety. Some file manager documentation call this kind of capability "prune-and-graft". This capability is "macroscopic" in scope, compared CMFiler -- Overview Ov-3 to the main modules, as it deals with the big picture of your disk organization. But CMFiler does much more than most file managers. In addition to the "macroscopic" prune-and-graft-type operators, you may do some microscopic things as well, like display the files in each subdirectory as you navigate through the tree, find a specific file anywhere on the disk, search for a text string in all or some of the files on the disk -- even view or edit a file, and delete it without having to return to the main file services module. This latter feature in particular makes disk cleanup a breeze! _____ Security Features. . . CMFiler incorporates security features which support its use on systems containing sensitive information: o You may specify a password, and change it at any time during a session, which must be given back to reenter CMFiler once it has gone to screen-saver mode (about 1-1/2 minutes after last keystroke from main screen display). This password is the bottom-most field in the data entry screen presented by the key combination Shift-F10 --discussed in further detail in Chapter 4. o You may force CMFiler into screen-saver mode with the key combination Ctrl-S. This is so that, if you want to secure access to your computer immediately, you don't have to wait the 1-1/2 minutes for the screen-saver and password to automatically be invoked. o If you set the option "Clear I/O buffers if located?" in the Shift-O Options screen, CMFiler will attempt to locate and overwrite all the DOS input/output buffers with the continuous string "CFCFCFCF..." before starting any file writing operations. This operation ensures that the file being written does not contain any stray data in the "slack space" of the last sector written that was hanging around from a previous I/O operation. ( ***DR DOS USERS:*** The option to clear I/O buffers should NOT be invoked if you are operating under DR DOS. This operating system responds very ungracefully to the buffer clearing feature. For this reason, I have set the default option to NOT clear I/O buffers.) CMFiler also employs a rudimentary check-summing routine to check the .COM and .OVY files each time they are loaded. This routine will sense any changes in the execution code and fixed data areas of either file, and warn the user of the corruption. Files may become corrupted as a result of an operating system error during data transmission, a sector going bad on a disk, or external tampering by a person or a virus. This check-summing feature can detect (and has detected) the presense of some older file infecting viruses, but may be foiled by modern stealth viruses, so DO NOT count on it for virus protection. There is no substitute for good antivirus software. I use and strongly recommend Wolfgang Stiller's Integrity Master. He is President of Stiller Research CMFiler -- Overview Ov-4 and a member of the ASP's Virus Information Panel, and a recognized expert in the anti-virus community. _____ Monitor Options. . . CMFiler should work with all reasonably current IBM-compatible CGA/EGA/VGA and monochrome monitors, though I have heard of some problems with machines under very early BIOS (Basic Input/Output System) versions. You may specify a type of monitor one of two ways: o When first run, if CMFiler cannot find a .CFG file containing previously specified user option data, and does not sense a monochrome monitor installed (which only supports one color set), it knows it cannot tell for sure what you have installed and will ask you to specify a monitor type by pressing C, L, T or M. Your choice is immediately recorded by CMFiler creating a .CFG file. If you have an LCD monitor other than Tandy, you may invoke a generic LCD color set with the letter L. For Tandy LCD's use T. (Tandy for some unfathomable reason inverts the function of the high-intensity bit in the color attribute.) If you have a "monochrome" monitor being driven by a color card, CMFiler senses the color card's presence, not the monitor's. Press M for this case to force the monochrome color set. You may also put one of these four letters in the command line, preceded by the character @, and bypass the initial question. _____ Precautions and Limitations. . . There are a few precautions and limitations the user should be aware of: o Terminate-and-Stay-Resident programs should NOT be launched from CMFiler. At best you will end up with a fragmented memory when you exit CMFiler, and at worst you will have a SYSTEM CRASH. o CMFiler requires a minimum of 197 KB of free memory to run. This permits generous memory allocations for the directory listings, a print spooler buffer, and a large copy buffer. During application launching, however, the resident portion of CMFiler can be made to occupy as little as 19 KB, using the "Small" footprint option of the "Kernel" command (letter K pressed from the main screen -- discussed more in Chapters 1 and 4). o Maximum directory size recognized by the main module varies from 300 to 1200 entries, depending on free memory available. If the directory size limit is reached, an informational note is given. The rest of the directory is inaccessible, as though it CMFiler -- Overview Ov-5 were hidden. This is a benign, non-damaging limitation. o The algorithms used by the editor module place certain limitations on it in "edit" mode which do not apply in "view" mode. If you attempt to edit a file which exceeds these limitations, the editor reverts to view mode automatically: o Files too large to fit in available memory in one shot, or o Files with more than 16,380 lines. o Files with lines longer than 8190 characters if editing in "NoWrap" mode. o The tree module limits the number of entries in a directory tree structure to 505 total subdirectories, and the total files to 3488. o The main and tree modules both limit the depth of directory nesting to eight levels (eg, "C:\1\2\3\4\5\6\7\8" is an example of the most deeply nested path allowed), and the length of path specifications to 66 characters (this is a DOS limitation). o A limitation of DOS itself which users frequently run into and are puzzled by, because of the cryptic error message DOS returns, is the maximum number of entries permitted in the root directory. This number is 112 for 5.25" disks formatted at 360KB and 3.5" @ 720KB; and 224 for 5.25" @ 1.2MB and 3.5" @ 1.44MB. The error message returned is "Access denied creating file". Be aware that the volume label and each subdirectory is an "entry", as well as each file. o Finally, CMFiler does not yet support mouse or 43/50 line EGA/VGA display capability. I have concentrated on packing the MOST COMPLETE set of useful operational features into the smallest, most intuitively organized package I could, and have not yet had the time (and do not yet have the hardware capability myself) to write and debug these additional user interface features. With respect to the mouse, my feeling is that ease of use has less to do with the HARDWARE interface between the user and the computer than the LOGICAL interface, and I have concentrated on writing the best logical interface possible. (In other words, a cumbersomely constructed program remains cumbersome, EVEN when you add a mouse!) If there is overwhelming request for addition of mouse support or 43/50 line display, I will consider adding it. Otherwise I will stick with the basics. CMFiler -- Overview Ov-6 _____ Assumption about User's Familiarity with DOS. . . It is assumed that the user knows at least a smattering about DOS system operation, and has at least a beginner's understanding of the use of the DOS COMMAND.COM processor, or other file management programs. I assume terms like "file", "subdirectory" and "path" need not be defined. If these are alien notions, however, there are any number of books on DOS written to different levels of proficiency which may be consulted as a resource. _____ Additional Note for Windows Users. . . Though not designed as a Windows application, CMFiler appears to be operating satisfactorily as a DOS program in the Windows environmemt. One nuisance feature will probably need to be corrected if you are running it under Windows, however. The default assumption on return from screen saver mode is that the disk directories have not been altered while CMFiler has been idling. Under Windows, this is not necessarily a valid assumption, since another foreground application may have operated on the directories CMFiler was selected to when it went into the background. Therefore for Windows users there is a switch which may be set, using the command Shift-O (where O is for Options) telling CMFiler to refresh the directory listings on return from the screen saver. _____ Assertion. . . I believe CMFiler is the most powerful and transparent file manager you will ever find anywhere for its price and size. It is being offered as a shareware utility in the hope that you will find it useful, and further that unregistered users will remit the required registration fee of $30 in recognition of the convenience CMFiler offers. Please remember that the shareware industry depends on the integrity, encouragement and financial support of its user public. _____ Special Thanks. . . . . .to Nick Capik, Tom Vavoso, Dave Herman, Gene Feaster and Edward Mendelson, who found most of the subtle bugs, pushed CMFiler far past my expectations, and challenged me to include features that turned out to be useful to us all; to Eric Tauck, who provided an excellent and inexpensive Assembly language programming environment, then tailored it to my needs, and gave me some inside dope on several undocumented DOS features; and to Wolfgang Stiller, who offered advice on CMFiler's self- CMFiler -- Overview Ov-7 checking features. Eric Tauck's Wolfware Assembler WASM can be had by sending $10 to Eric Tauck, 1304 Deerpass Road, Marengo, IL 60152. Wolfgang Stiller's Integrity Master anti-virus and data security system can be had by sending $39.50 to Stiller Research, 2625 Ridgeway St., Tallahassee, FL 32310. CMFiler -- Overview Ov-8 ******************************* * * * CMFiler -- Version 5.35 * * * ******************************* TUTORIAL -- Chapter 1: File Handling: _____ GETTING STARTED , or the "Kernel" and the "Overlay": As mentioned in the OVERVIEW above, I refer to the 19 KB CMFILER.COM file as the "kernel", the vital part of the main module, and the 82 KB CMFILER.OVY file as the "overlay", which contains the rest of the main module and the editor and tree modules. Physically breaking the program into two files served two purposes -- it got around an arcane 64 KB limit on .COM files imposed by DOS, and it let me give you two options for how much of the program to leave resident in memory when launchig applications from CMFiler (more in Chapter 4). For now, copy CMFILER.COM and CMFILER.OVY into the root directory of your hard disk or a working floppy using your good ol' DOS COMMAND.COM processor, and save a write-protected copy for your library. With the DOS system prompt showing the drive these two files are now on, run the kernel CMFILER.COM by entering "cmfiler" or "CMFILER". The DOS command processor will load and execute CMFILER.COM, which in turn will find and load the overlay CMFILER.OVY. The whole 101 KB (19+82) is now residing in memory, ready to respond to commands. The first thing you will likely see is a request for monitor information. CMFiler cannot distinguish between a color monitor and an LCD monitor, and the default color set for the color monitor is a poor choice for LCD monitors. When you see the message, press C, M, L or T (some Tandy LCD's employ a backwards convention on the high intensity attribute, and thus a separate color set has been dedicated to them). As soon as you press one of these letters, you will see disk activity. CMFiler is creating a file of user configuration data (called CMFILER.CFG) in the same directory the .COM file is in. It will update this file as you select other setup options. _____ Rename CMFILER to Spare My Fingers. . . Now, feel free to rename CMFILER.COM to "CF.COM" for short, and the overlay and configuration files from CMFILER.OVY and CMFILER.CFG to "CF.OVY" and "CF.CFG". (It is important to keep all these files named THE SAME, by the way.) In fact I will refer to them simply as "CF" from here on, since that results in fewer keystrokes for me! Put the cursor on the line reading "CMFILER COM" and press the letter R (for "rename"). A window will open up at the bottom that says: Rename CMFILER.COM to >CMFILER.COM< with the cursor blinking on the first position in the data entry field denoted by the "> <" pair. (CMFiler is assuming that you want to rename just the CMFILER.COM file, since the most frequent use of the rename facility is renaming single files; and is offering you the same name as the "default" entry in the new name field, since often when you rename a file, you may be only changing a few characters.) In this case we want to rename all the files that start with "CMFILER"; that is, we would really like to use the DOS "wild card" convention "*". If we were renaming this family of files from the DOS prompt, we would type in the command "ren cmfiler.* cf.*". In the CMFiler rename facility, the upper line is the first parameter of the DOS rename command, the lower line the second. We therefore want the upper line to read "CMFILER.*". To do this, press either the up arrow or PgUp, and press Tab to move over to the "C" in "COM". Type "*" and press Enter or down arrow. Now the window reads: Rename CMFILER.* to >CMFILER.* < Simply type "CF.*" and press Enter. The files are now renamed. This quick exercise sounded complicated when you read it, but won't be when you try it. And it illustrates a few "nice touches" I have tried to build in to minimize your keystrokes. From here on the explanations are not so detailed. I recommend you fiddle with scratch disks initially, until you are familiar with all of CF's capabilities. If you are running DOS Version 2, put CF, both the .COM and .OVY files, on one of the paths defined in a DOS "path" command, so that it can "find" itself after running other applications. This is not necessary under DOS Version 3 and later. _____ The Screen. . . You should by now have noted an economy of screen usage. The left panel shows the contents of the root directory on the default drive. Line 1 of this active panel shows the disk volume name if any, and a prompt area for four display enhancement features: the key combination Ctrl-O (denoted by ^O to save space) allows selection of one of seven file Ordering schemes; ^H toggles the "Hide" mode switch; ^C toggles the "Compare" mode switch; and ^M allows specifying a file "Mask". Line 2 shows the path to the current directory, whose first 20 entries are CMFiler -- Chapter 1 1-2 displayed in lines 3-22. Line 23 gives vital information about the disk, such as room left, and lines 24-25 contain an abbreviated help screen. The thick versus thin sections of the vertical line to the left of the file list denote the relative position and size of the current screen display within the full directory listing. If you do not press a key within about 1-½ minutes, the screen goes into screen-saver mode. Just press any key to return to the main display. You may force the screen-Saver mode with Ctrl-S. _____ The Help Area. . . The two-line help area at the bottom of the screen contains a set of abbreviated cues to assist with the recollection of the mnemonic single- key commands. With no "modifier" keys pressed [i.e., the Shift-, Alt- and Ctrl- keys all up], the help area shows the operations available with the unmodified keys, with the mnemonic code highlighted. These are typically the most frequently used operations; the letter C for "Copy file(s), E for "Edit file", D for "Delete file or directory", T for "Tag file", the number 1 for "toggle the file Read-only attribute", and so forth. Additional commands are available which use similar mnemonic devices, but with the keyboard modified by Shift-, Alt- or Ctrl-. Press one of the Shift- keys, and notice the change in the bottom lines. These are the commands enabled by the letters shown in highlight, modified by the key you are holding down. Press Ctrl- and Alt- in turn. All these operations, both "unmodified" and "modified", will be explained as we go along. Just be aware that the visual cues for the modifier keys are there when you want them. _____ More on the "Modifier Keys". . . Incidentally, there is some rationale for which of the Shift-, Alt- or Ctrl- keys was used as the modifier for a particular "modified" operation, and there are some devices which may help you remember the modified keys as well as the more straightforward mnemonic devices of the unmodified keys: o The modifier "Shift-" is often used for operations involving transfers of control or data to or from the other panel. For example, Shift-Enter, when the cursor is on a subdirectory entry, means display this subdirectory in the other panel and jump across to it. Other commands which follow this convention, and which you will encounter in more detail, are Shift-Left/Rt Arrow, Shift-P, Shift-*, Shift-\, and Shift-F. CMFiler -- Chapter 1 1-3 o The modifier "Ctrl-" is most often used to "toggle" the state of a "switch" or "tags" -- that is, to invert something. For example, Ctrl- H toggles the state of the "hide switch" , i.e., if Y ("yes" or "on") it goes to N ("no" or "off"), if N it goes to Y. Other examples include Ctrl-O, Ctrl-M, Ctrl-C, Ctrl-A, and Ctrl-L. o The modifier "Alt-" is most often used just to indicate an operation associated with a mnemonic alphabet key, but for which the unmodified key was already in use as a mnemonic for a more frequent operation. For example, C means "Copy", and is one of the most frequent operations; Alt-C means "add file spec to Command tail", and is used far less frequently. (In the editor, Alt-modified keys are used a LOT, since the unmodified keys are used for typing text!) _____ Two Panels. . . Each of two "panels" corresponds to a "path" to files, in the DOS vernacular. Open the right panel by pressing the right arrow. You will be prompted at the bottom of the screen to specifiy a drive letter. (Lines 24-25 become the "dialog" area for information to you about what CF is doing, or what it is waiting for you to do.) Just press the letter corresponding to a valid drive -- don't press Enter, just a letter key. The root directory of that drive will be shown in the right panel in the same format as the left panel. The bright yellow color of the path specification on line 2 and the blinking cursor now identify the right panel as the "source" path. The left panel has become the "target" or "destination" path for copy and append operations. Whenever CF is in "compare" mode and the cursor is on the name of a file in the source panel that also happens to exist anywhere in the target path, the target panel display is adjusted so that the file appears in the panel, and its date/time signature is put in high- intensity to catch your eye and show you the duplication. If the date, time and size of the two files are not the same, the date/time signature of the NEWER file will blink. You can toggle compare mode off and on with the key combination Ctrl-C (the mnemonic is "compare"). _____ Color Palette. . . For display in CGA/EGA/VGA systems, CF has four choices of color palettes. The command Ctrl-P (for Palette) lets you cycle through the choices with the Spacebar, and select a different color scheme with Enter or return to the original one with Esc. The choice is permanently recorded in the .CFG file (discussed in more detail later). CMFiler -- Chapter 1 1-4 _____ Alphabetic Case Options. . . CF also has four options for the alphabetic cases used in the panel displays. The command Ctrl-E (for casE) lets you cycle through the choices with the spacebar, as in the Palette above, which are: 1) files and directories all upper case, 2) directories in upper case, file in lower, 3) all in lower case, and 4) all in "modified-Tauck" convention, where all letters are lower case except the first and any that follows a non-alphabetic character (eg, Cmfiler.Com or Read-Me.1St). I have found this last convention by far the easiest to read. _____ Cursor Movement. . . Shift back and forth with the left and right arrow keys. You are in effect switching source and target paths. Use the up/down arrows, PgUp/PgDn, Home and End keys to move the cursor within a panel. PgUp moves the cursor to the top of the panel if it was not already there, and then moves up 19 lines in the directory. PgDn is similar for the opposite direction. Home goes to the first line of the directory, End to the last. The command G (for "Go to...") lets you type in a file name to move the cursor to within the directory listing. As you type, the cursor is repositioned to the first file described by the character string you are building. When you have come to the file you want, press Enter or Esc. Alt-G is the equivalent "Go to. . ." for subdirectories. In "Compare mode", whenever there is a duplicate file name highlighted in the opposite panel, you may jump directly across to it with the move Shift-Lf/Rt Arr, vice the unmodified arrows. _____ Switching Drives or Disks. . . CF cannot tell when you have changed disks in the drive whose contents are shown on one of the screen panels. You have to tell it by putting the cursor in that panel and pressing Shift-R (for "Refresh") or N (for "New drive") and the letter designator for that drive at the ensuing prompt. If you want to switch drives, say from A to B for the right-hand panel, put the cursor to the right, press N and B. Sometimes when you are doing single-panel operations, like constructing a note set or editing files, it is a distraction to have both screen panels open at once. To close the right-hand panel and return to single left-hand panel display, put the cursor in the right- hand panel and press N and Enter. CMFiler -- Chapter 1 1-5 _____ Subdirectories. . . Make a new subdirectory in the source path by pressing M (for the DOS command "Mkdir") and entering a name. Find it in the display in alphabetical order, move the cursor to it and press Enter. Note the new path on line 2 of the screen display, and only the "<Parent>" entry in the file listing. Go back to the parent directory by pressing Enter with the cursor on the "<Parent>" entry, or P with the cursor anywhere in the panel. You can navigate down and back up through the directory levels in a path this way, one level at a time. If you are several levels deep, there is another quicker way back to the root directory than by hitting P repeatedly, and that is the backslash key \. It works like the DOS command "cd \". To put a subdirectory from the current source panel list into the target panel, put the cursor on its name and press Shift-Enter. The subdirectory is listed in the opposite panel, and the cursor shifts over to it. In similar fashion, Shift-P puts the source panel's parent directory into the opposite panel, and Shift-\ puts the source's root into the opposite panel. Finally, Shift-* puts the source directory itself into the target. This is handy for quickly setting up the same panels side-by-side for ZIPping/unZIPping, discussed in Chapter 4. Remove a subdirectory by placing the cursor on it and pressing D (for "Delete", which I use interchangeably for file deletion and subdirectory removal). Note that the subdirectory has to be empty first -- a DOS safeguard. _____ Copy Some Files, then Do It with Tags. . . Put the cursor on a file name and press the letter C. This copies the file from the source to the target path. "Tag" several files with the letter T or the Spacebar. Now press C to copy this group from source to target. Clear all the tags with A (tag/untag All). Press A again, and see that all the files are now tagged. Untag an individual file with T. ("T" actually toggles the state of an internal tag bit assigned to each file and used for temporary marking purposes only. "A" clears all the tags if any were set, or sets all the tags if all were clear. No information is changed on the disk itself. These are "volatile" tags, maintained only until the directory is re-read for some reason, such as a file deletion or a copy operation into the directory.) CF looks first at the space available on the target path before it starts to copy. If it doesn't see enough room free, it doesn't start the operation, and alerts you to this limitation. This prevents write errors, messed up file allocation tables and incomplete files that can result when space runs out during a copy operation. CMFiler -- Chapter 1 1-6 CF has several special features in the copy operation: o If an identical file exists in the target path -- same name, extension, date, time AND size -- CF does not normally copy the source to the target, as this would be wasted motion, on the assumption that the files are identical. This "no overcopy" feature is controlled by one of seven switches which may be toggled in the user setup menu brought up with the command Shift-O (for " user Options"). It is sometimes useful to change its state. o If a file by the same name but newer date/time is found on the target, CF will ask you specifically to verify that you really do want the newer file overwritten. o If the source file has length 0 bytes, or if the source and target files have the same date/time but the source is smaller, CF will ask for overwrite confirmation. This provides some protection against overwriting a good file with one which has become corrupted by a previous copy error. o If a file by the same name but with the read-only attribute set is found on the target, CF will ask you to verify that you want it overwritten. (Likewise if the target file is hidden and the hide switch is on.) _____ Tagging, Backing Up. . . With a couple of files tagged, look at the line just below the last line of the directory listing. You will see the space in use in the current directory ("KB Used"), the amount of disk space occupied by any tagged files ("Tagd") and the space still free ("Free"). Also, in the line below will appear after each tagging operation the current number of files tagged. Disk space is expressed in kilobytes, in integer multiples of the disk media cluster size, so what you see is the amount of space ACTUALLY tied up on the disk. (If your disk is a 5.25" DSDD floppy its clusters are probably one KB each. Every file takes up at least one cluster, so a 1-byte file takes up a one KB of disk space, the same as a 1024-byte file.) Assuming the amount of space represented by tagged files is less than or equal to space available, press B to back up all the tagged files. CF's convention for assigning backup file names in this operation is to reuse the fiorst two letters of the extension (filling blanks with exclamation points), and then make the last letter of the extension a tilde character (~). Thus the backup should always immediately follow the primary file in any alphabetical listing. CMFiler -- Chapter 1 1-7 _____ Moving Files. . . With the panels selected to different subdirectories on the same disk, one or more files may be "moved" from one subdirectory to the other. This operation does not read and write the file data clusters, but only changes the subdirectory table entries, so large files may be moved around quickly. Tag files if desired, as with Copy, and press the move command Shift-C (instead of C -- think of moving as just another kind of "copying", but you are "shifting" files to a different directory instead). If the conditions are not satisfied for moving the files (e.g. the directories are not on the same disk), CF will copy the files to the target path, but will not delete the tagged files in the source. You may delete the tagged files with two more keystrokes if you wish, but CMFiler does not assume this is what you meant. This encumberance is deliberate; because CMFiler is so fast, I have made it require confirmation whenever any file destruction is requested. _____ Deleting a File. . . With the cursor on a file and no files tagged, pressing D results in deleting the file under the cursor, after confirmation. If one or more files are tagged, they will be deleted after confirmation, not the file under the cursor. Alt-Tags, discussed below, are treated the same as normal tags as far as the delete operation is concerned. On hard disks, the default configuration of CF actually performs what I will call a "soft" delete for this operation. The files are not deleted using the DOS delete function, but rather are redated to the current date and time, and moved into a directory created by CF, called "CF_TRASH.CAN". If you delete files from your hard disk by mistake, they are RELIABLY recoverable just by switching to the CF_TRASH.CAN directory and moving them back to the directories they came from using Shift-C. If you delete a second file by the same name as a file already collected in the CF_TRASH.CAN directory by a previous soft delete operation, CF tries to rename this second file by replacing the last character in the extension with a "1". If this name is already in use, it tries to rename with a "2" instead, then a "3", and so on, through "9". Thus, you are assured under all reasonable circumstances of not losing any deleted files, even duplicates. The only problem is that you may have trouble telling which duplicate is the original, as CF redates each of them during the "soft" delete. Each time you select a new drive in the main module, CF looks to see if it is a hard drive (A and B are always taken to be floppies), creates CMFiler -- Chapter 1 1-8 the directory CF_TRASH.CAN if it is not already present, and then looks in CF_TRASH.CAN for the presence of files with any date earlier than the current date. If it finds any, it will ask you if you want to purge them -- that is, perform the "hard" DOS file delete on yesterday's trash. You have the options "yes", "no", or "Enter to view" to see what is in the thash can. You probably want to keep the CF_TRASH.CAN as uncluttered as possible, just to avoid tying up disk space needlessly. If you prefer to "empty the trash" less often than daily, be prepared to be pestered with the same question the first time you select that disk each day! (The D command always performs a "hard" delete in the CF_TRASH.CAN directory -- this is the one exception.) This "soft" delete facility is NOT intended as a means of backing up files, but rather is built in SOLELY for the purpose of RELIABLE recovery from inadvertent file deletion. An additional delete option is available -- Ctrl-D, or "hard" delete. This operation performs the DOS delete always, regardless of the type disk selected. Use it when you KNOW you will not want to recover the deleted files. And if you are REALLY sure of yourself, you can turn D from soft delete to hard delete. There is a switch available for this purpose in the Shift-O user Options menu mentioned above. _____ The Tagging Convention Expounded on. . . For all the above commands (copy, delete, move, back up), the operation is performed on ALL THE TAGGED FILES in the source panel, if ANY are tagged, and only on the file at the cursor if NONE are tagged. Some file managers offer different commands for "copy tagged" and "copy file at cursor", and so forth. I have always found this unnecessarily complicated. For the FEW occasions in which you have a bunch of files tagged to do one of these operations (say you want to copy them), and you discover just before you start that you really wanted to do some other operation on just one of them first (say you realize one of them is out- of-date and you want to delete it), you will have to either untag them all with A, do the operation on the one file, then retag and do the original operation; OR just postpone the one-file operation. For this example, it is easier just to toggle the tag on the one out-of-date file off with T, copy the other bunch, clear the tags, and delete the one. It becomes just a matter of a little thought about the order in which you do things. The "view" operation (discussed in Chapter 2) does NOT clear existing tags. So, suppose you are cleaning up a disk, tagging files that you recognize by name as no longer needed in preparation for a single, massive delete, and you come to one you aren't sure about. Put the cursor on it, press Enter (the "view" command), browse through it and CMFiler -- Chapter 1 1-9 decide if it's a keeper, and Esc from view mode. Note the previously placed tags are still there, and the cursor is still on the mystery file waiting for you to decide whether or not to tag it. _____ Renaming a File OR a Directory. . . Since we'e already done this, I'll just briefly say that it works for directories, too. A word about the wild card character "*". In the earlier exercise, we used it in the first window to declare that we wanted to rename all the files with "CMFILER" as the name, and any extension, to "CF" with the same extension. You may use the "*" in the name field of the first window instead of the extension, but not in both. Used in the name field, it means "change this extension, wherever it appears, to this other extension". This option is less useful. If used in the first data window, the "*" MUST also be used in the second window in the same position. CF always senses the use of "*" in the first window, and seeds the second window with this character in the right position. The "*" may be used in the second window, even if not in the first, as a shorthand for "keep the same name (extension)". For example, if you wanted to rename just "CMFILER.DOC" to CF.DOC", put the cursor on "CMFILER DOC" in the source panel, press R, type "CF.*" in the lower window, and Enter. Saves some keystrokes. This is a wild card convention taken from DOS. (Sorry to you DOS heavies -- for simplicity I chose not to complicate things by including "?" in the wild card library for this facility!) _____ Some Additional Tagging Options. . . In addition to T (which toggles the state of an individual file's "normal" Tag) and A (which clears or sets All tags), there are some more tagging operations. Alt-T applies an "append tag", discussed later. Alt-M tags all the files in the panel with the same naMe as the file under the cursor, Alt-E same Extension. Alt-D tags all files in the panel with the same Date as the file at the cursor, Alt-N tags all files Newer, and Alt-O Older. Alt-P tags in the oPposite panel all the files with the same names as files tagged in the source panel. (This is good for updating to a floppy only the files which were already on it.) And finally, Ctrl-A toggles the state of All tags in the panel. If, for example, you wanted to copy all .COM files, put the cursor on any .COM file, press Alt-E, and C. Or suppose that, at the end of the day, you wanted to copy/update all the files written or revised today. Just put the cursor on any file with today's date and press Alt-D and C. Then suppose you wanted to delete all the earlier files. Press A to clear CMFiler -- Chapter 1 1-10 the tags, Ctrl-O and D, and confirm the deletion as requested, after a final check of the screen. _____ Copy with Rename. . . You may copy a file and rename it in one operation. Only one file at a time may be copied in this way. The command is Alt-R (copy with Rename). It operates only on the file at the cursor. _____ The File "Freshener". . . Suppose you have a floppy disk with backups for some of the files in a hard disk directory, and you want to freshen them periodically. With either panel set up with the primary directory whose files you are backing up, put the backup floppy in a floppy drive, arrow across to the other panel and press N and the drive letter to bring up its root directory (now in the source panel), and then just press Shift-F (for Freshen). CF tags all the backup files in the source panel if none were already tagged, or leaves existing tags as-is if some were tagged; then tags all the files in the opposite panel with the same name as tagged files in the source but which are NEWER; then copies these to the source; and finally updates the source panel display, leaving the primary directory in the target panel display tagged to show you what was copied. Just four key strokes! No excuses ever again for not backing up files. _____ Different Ways to Show the Files. . . Ctrl-O (for "Order") sets a screen which gives seven choices for file ordering, with the cursor blinking on the current selection. Press a number key 1 through 9. The files will now be reordered in the new scheme. The options for ordering by date/time are particularly useful in the visual sense when backing up just the files revised today, as in the example above. _____ The Data Entry Window. . . The data entry window you encountered in the renaming exercise responds to most of the usual line-editing key presses: o Insert toggles the mode between Typeover and Insert. The mode stays set for each subsequent entry. In Typeover mode, any default entry is cleared if the first keystroke is an alphanumeric character. CMFiler -- Chapter 1 1-11 o Ctrl-Lf/Rt Arrow and Tab/Shift-Tab go right or left to the space following the next blank or punctuation mark. o Shift-Lf/Rt Arrow go to beginning or end of data field. Home goes to the beginning of the field. o Lf/Rt Arr, Bksp and Del perform the usual functions. o End goes to the blank after the last non-blank character. o Alt-Keypad permits entry of any ASCII code as a decimal number. Hold down the Alt--key while you type in a number from 1 to 255 on the numeric keypad. When you lift the Alt--key, the IBM symbol for that ASSCII code will appear in the window, and the cursor will advance a space. o Ctrl-D deletes to the end of the line. o Esc aborts the operation. o Down Arrow is equivalent to Enter. In some cases, Up Arrow moves up a line. (The rename facility in the main module and the "replace string" facility in the editor use this convention.) For entering file names and subdirectories, all letter keys are registered as upper case, regardless of Caps Lock or Shift-key positions, just for the sake of uniformity and ease of alphabetizing. For command lines parameters, which may be case-sensitive, both cases are enabled. _____ Disk Space Occupied versus Actual File Size. . . Now take a look at the file listing. You see the name of the file, date, time and size in KB. As with the disk space information just below the file list display, size is in integer multiples of clusters occupied. If you want to see exactly how big a file is, in bytes, press "+" to expand the size field. (I had to give away the file time to do this and still keep the two panels readable.) Shift back to the "contracted" kilobyte form of file size with "-". _____ File Attributes. . . Also in the file list, to the far right in each panel, you will probably see A's. This means that the DOS "Archive" attribute bit is set in the file attribute byte. DOS sets this bit everytime it operates on a file. CF lets you operate on this bit and the other bits in the DOS file attribute byte -- "Read-only", "Hidden", and "System". Before doing this exercise, look at the top line of the CMFiler -- Chapter 1 1-12 display. If you see "^Hide=N", that means that files with the DOS "Hidden" attribute set will be displayed anyway -- i. e., the CF "Hide switch" is off. Chances are you will see "Y" instead of "N", meaning that the Hide switch is on -- the default setting. In this setting, files will disappear from view as you set the DOS hidden attribute, so we need to toggle the hide switch to "N". Press Ctrl-H to toggle the hide switch off. Either tag one or more files, or position the cursor on the file whose attribute(s) you want to set, and press 1 to toggle the state of the Read Only attribute, 2 to toggle the Hidden attribute, 3 to toggle the System file attribute, 4 to toggle the Archive attribute, or 0 (zero) to clear all attributes. You may also toggle the hide attribute (with 2) of a subdirectory, but this must be done one subdirectory at a time. Note that "hiding" a file makes it invisible to CF only when the hide switch is set on, as shown in the top line. Toggle this hide mode off and on with the combination Ctrl-H (discussed further below). Decide for yourself which mode you prefer. Some people like to hide the "overhead" files and directories on their disks, and leave the hide switch on as the default setting to "clean up" the display. _____ Changing the Date/Time Stamp of a File. . . You may change the date and/or time of a file by putting the cursor on it and pressing Alt-F. A data window opens for you to first enter the new date, using the current date in the file's date/time stamp as the default, and then the time. This operation is not permitted on Read-only files. _____ "Alt-Tagging" and Appending. . . Suppose you have two files that you want to stick together as one, heel-to-toe. Tag them with "append" tags with the key combination Alt-T or Alt-Space in the order in which you want them to be concatenated, and press C. CF will offer you a filename for the new concatenated file consisting of the name of the first file Alt-Tagged plus the extension ".APF" (for APpended File). You may edit or accept that name as given. Then it creates this file in the target path and appends into this file each of the Alt-Tagged source files in order. You may concatenate up to 35 files at a time this way. The order in which the file was Alt-Tagged is shown in the character that appears to the left of the file name as it is tagged (1-9, then a-z). If you had pressed B instead of C after affixing the Alt-Tags, the concatenated file would have been written as a backup into the source path instead of the target. CMFiler -- Chapter 1 1-13 _____ Printing a File. . . You can print a file to the parallel printer just by putting the cursor on the file and pressing L (print fiLe). The file will be put into a special print "queue" for printing to line printer 1 on the parallel port as a background process while you are doing other things, like editing another file, updating disks, etc. Up to five files may be put in the print queue, which may be viewed with Shift-L. At times the printer may halt momentarily during disk operations. CF gives preference to disk operations over printing, to avoid any conflict in time-critical operations. You may terminate printing with Ctrl-L. This actually clears the entire print queue. To force a form feed at the end of the file you have just queued, press Ctrl-F before you queue the next file. CF sets an internal flag to check that the last character sent to the printer from that file is a form feed. If it is not, then it sends one. (Ctrl-F is active when no file is printing, also, as a way of form-feeding the printer from the keyboard.) _____ Making Some Notes About Your Files. . . If you are like me, you sometimes forget what a program with a strange name does, or what a particular data file is. CF lets you write notes to yourself about any file. Press Ctrl-N and a Notepad opens up in the opposite panel for editing. You can type a little narrative for each file or subdirectory in the directory. The editing keys work much the same as in the line editor, except that you are limited to 39 characters for each entry. Each time you call up the notepad, it appears as it did the last time you edited it. You may just browse with the up/down arrows, PgUp/Dn, Home/End, edit or add, etc. Leave the notepad with Esc or Ctrl-Enter. If you use Esc and did any editing, you will be asked if you want to save that edit of the notes. From the "edit Notes" screen you may also view or edit the file opposite the note without leaving the edit Notes environment, just by pressing Alt-V or Alt-E. You may also attach a normal tag to the file with Ctrl-T or Ctrl-Space ("T" and "Space" are not available, since the notes editor would take it to be text), or an append tag with Alt-T or Alt-Space. A "view Notes" command Shift-N simply replaces the target panel display with the notes for the source panel, but all the file and directory service commands, including the source-to-target commands such as Copy and Shift-C move, are still active. The notepad is contained in a hidden file call "NARATIVE.CF", and notes follow the file when it is copied or moved to another path or CMFiler -- Chapter 1 1-14 renamed. If you delete a file, its notes will be lost the next time you call up the notepad. You may make the NARATIVE.CF file unhidden with one of the user Options in the Shift-O menu. If you are a 4DOS/NDOS user and you already have notes written about your files and directories in this convention, you may convert the DESCRIPT.ION files to the CF note file format NARATIVE.CF using the program DESC2NAR.COM provided in the CMFiler file set. This program does not alter any DESCRIPT.ION files, and retains the notes already in any existing NARATIVE.CF files. Read the separate documentation in DESC2NAR.DOC file. _____ Printing a Directory Listing. . . Press Alt-L to send a directory Listing to the line printer. If you do this from either of the Notes displays, you also get a listing of the notes, and the file size entries is either the abbreviated or full value, depending on the display mode set in the directory table (toggled with + and -). _____ Comparison Mode. . . At the top of the screen you see a message "^Comp=Y". The "Y" means "yes", the compare "switch" is enabled, so that any file in the target panel whose name is the same as the file in the source panel will be shown and its date-time stamp highlighted for easy identification. If the files have different date-time, the newer version will be blinking. You may toggle this switch with the key combination Ctrl-C. In comparison mode there is a useful feature which enables you to get quickly to a file with the same name in the opposite panel. In arrowing back and forth between panels in comparison mode, with some files by the same name in each panel, you probably noticed that the target panel shifted as necessary to bring the duplicate name into view, but as soon as you shifted over to the target panel, it "remebered" and adjusted the display back to where the top line and cursor had been left, and you lost the duplicate file from view. But suppose you had seen a more recent file in the target panel, as evidenced by the blinking highlight, and you REALLY wanted immediately to arrow over to it and copy it into the source. The Shift-Left/Rt Arrow combination does this. It resets the target panel display parameters so the cursor goes right to the matched file name. CMFiler -- Chapter 1 1-15 _____ Hide Mode. . . Also at the top is the message "^Hide=Y". This means that hide mode is enabled -- the screen display will not show any "hidden" files -- those with the hidden attribute set. This is handy for cleaning up your displays -- just hide the overhead! You may toggle the state of this switch with the key combination Ctrl-H. The current state of these two switches is set as the default any time you do a Shift-F10 edit, discussed in Chapter 4 on application launching. _____ Mask Template. . . Also at the top is the message "^Mask=*.*". This is a mask that lets you sift out all but files with a certain characteristic. For example, if you want to see only the .EXE files, press Ctrl-M, Tab, type "EXE", and Enter. Tab and Shift-Tab position the cursor on the extension and name fields, respectively. The left and right panel masks are independent. _____ Displaying System Date and Time. . . The display of system date and time may be toggled on or off with the "5" key (sorry, no mnemonic). Its state is saved in the configuration file with Shift-S. _____ Changing or Adding a Volume Label. . . Press V and a data window opens at the bottom for you to enter a new volume name for your disk. The existing volume label is offered as a default for editing ease. _____ Some Safeguards. . . As noted above, you can't remove a directory unless it is void of files. This is a built-in DOS safeguard that CF passes along to you, since it uses the DOS file handling services. In addition, CF asks you to verify any requested delete operation; any requested copy operation that would overwrite a file of the same name but newer date/time in the target path, a read-only file, or a hidden file with the hide switch on. In addition, if you attempt to copy or move any files out of the CMFiler -- Chapter 1 1-16 CF_TRASH.CAN directory, you will be asked to confirm that you REALLY want to do that. This precaution is taken because, when files are put in the "trash can" by a delete operation, their date/time stamp is changed to be the date and time they were DELETED. Therefore it is probable that files in the trash can will appear to be NEWER than identically named files in other parts of the disk. For this reason, files should only be moved or copied out of CF_TRASH.CAN with GREAT CAUTION, lest they overwrite files that are actually more up-to-date. _____ Saving User Setup Options. . . You have already read about three cases in which features can be reset from their default (or "as-delivered") condition using a special user Option menu summoned by Shift-O. The "soft" delete can be redefined as a "hard" delete, the NARATIVE.CF notes file can be redefined as not hidden, and the identical-file overcopy switch may be set on or off. There are seven such features, total, available for setting to your specifications. When you visit this menu and then leave by pressing Enter, the configuration file CF.CFG is updated so that these switches settings are remembered the next time you run CF. The nature of these seven switches is such that you probably will not change them often. They represent your preferences as to a standard configuration of features. When you press Shift-O, you will see the following menu: -------------------------------------------------------------------- Move cursor with Up/Dn Arrow. Type option desired. Define F1 as Help? N Define "D" as HARD Delete? N Clear I/O buffers if located? N Overcopy files with same date/time/size? N Refresh directory contents after Screen Saver? N Assign Hidden attr to NARATIVE.CF file? N Assign Read-Only attr to NARATIVE.CF file? N Turn Screen Saver off? N Monitor (C=Color, L=LCD, T=Tandy LCD, M=Mono) C Press Esc to cancel changes, Enter to accept. -------------------------------------------------------------------- These nine "switches" represent setup features that various users have asked for. The default settings are all N ("No"). Any setting may be toggled between Y and N by putting the cursor on it using the Up/Dn Arr keys, and pressing the spacebar. When you have reconfigured the way you wish, press Enter. Esc exits with no changes. Here is an explanation of each feature: CMFiler -- Chapter 1 1-17 1. In keeping with the convention most often used, the F1 key is assigned as a "Help" call in the editor and tree modules, and can be so assigned in the main module by resetting this switch to Y. The sacrifice is loss of F1 as a user-defined application. 2. For those who do not wish to use the "soft" delete feature nor be bothered with the directory "CF_TRASH.CAN", the D key may be reconfigured to "HARD Delete", identical to Ctrl-D by resetting this switch to Y. (Discussed above.) 3. The I/O buffer clearing feature for data security during file writing operations runs into problems on some system configurations with DR DOS 6.0 as the operating system. It has been set to a default mode that does NOT clear buffers before writing. If you want to invoke this security feature, you have to reset this switch to Y. This feature appears to work satisfactorily in all versions of MS-DOS, but DO NOT invoke it under DR DOS. 4. In the default setting, CF does not waste time during file copy operations overcopying any file in the target path that are reported by DOS to be the same date/time and size as a file in the source path. However, sometimes you might want to mass-overwrite files on a backup directory or disk that are suspect, even though they may appear to be identical. Just set the Overwrite switch to Y. 5. For Windows users, if you run CF in a window, it does not have any way of knowing when it returns from the background to the foreground whether any other application has written to the directories that it is selected to. In the default setting, it does not refresh the file listing (reread the directory tables). Windows users may want to reset this switch to Y. 6. and 7. The NARATIVE.CF file, created in each directory as necessary to contain file and subdirectory notes, may be assigned the Hidden and/or Read-Only file attributes for neatness of directory display and/or protection from inadvertent deletion. 8. The automatic screen saver may be turned off if desired, to give the sole screen-saving function to your favorite resident screen saver. 9. Finally, the color attribute set may be changed by pressing C, L, T or M. If, for example, your system has a color card driving a green-screen monochrome monitor, you probably would be more satisfied with the monochrome color set invoked by M than the default color set C. There are other features of CF, particularly in the display options, which you may reset lots of times in process, but which don't need to be recorded permanently each time you change one. For example, I leave the CMFiler -- Chapter 1 1-18 file ordering scheme set at the default value of "1" (straight alphabetical), but sometimes I want to look at files in the order I last modified them. I will temporarily reorder using the Ctrl-O command, but I still want CF to come up with ordering scheme "1" next time I run it. Conversely, the default setting for the "Hide" switch is "Y" (since that's what most users wanted), but I prefer to see everything, so I want it permanently set to "N" (for No, don't hide files with the hidden attribute). These values are savable. The other in-process option features that are savable are the Compare mode switch, the resident Kernel size, and the date/time display on or off. They are saved 1) whenever the Shift-O setup Option menu is exited with Enter, 2) whenever the Shift-F10 user- defined application menu (discussed in Chapter 4) is exited with Ctrl- Enter, or 3) by pressing Shift-S (for Save options). _____ Help. . . In addition to the two-line mini-help area at the bottom of the screen, a three-page summary may be summoned on-line at any time in the main module of CF by pressing H. PgUp and PgDn page through the help, and Esc exits back to the main screen. _____ Command Line Parameters. . . CF supports optional command line parameters to specify the initial path for the left panel, right panel, file mask and color set, in the syntax: cf [pathspec1[\mask] [pathspec2]] [@color] where pathspec1 and pathspec2 are directory specifications to the initial directories to be displayed in the left and right panels, mask is any valid mask specification, and color is C, M, L or T for the CGA/EGA/VGA, monochrome, LCD or Tandy LCD color attribute sets. The mask may be attached to either pathspec or stand alone, but must be of the form "*.ext". The color specification may appear anywhere. Examples of valid command lines might be: cf c:\assembly\*.asm c:\pcw @c cmfiler c:dos @m CF UTILS WP51\*.DOC CMFILER @C *.EXE CMFiler -- Chapter 1 1-19 _____ Quitting CF. . . There are two commands for exiting CF; Esc-other key and Alt-Q. The Esc-other key combination reestablishes the default drive and its current directory as CF found them. The Alt-Q combination leaves the default drive and its current directory as it appears in the source panel. In either case, if you were printing a file, you will be asked if you really want to quit, since the print spooler does not stay resident and quitting will terminate file printing. You may answer N. CMFiler -- Chapter 1 1-20 ******************************* * * * CMFiler -- Version 5.35 * * * ******************************* TUTORIAL -- Chapter 2: File Viewing and Editing: CF has a built-in line editor, which simplifies file viewing and editing -- even .COM and .EXE files. Since it is part of the package, there is no loading delay. It is ready when you are. _____ Viewing a File. . . Want to see what's in a file? Put the cursor over a file -- any file will do; ASCII text, PC-Write, .COM, .EXE -- and press Enter. CF loads the selected file in memory for viewing. _____ Record Delimiters. . . The default display mode for "record delimiters" [carriage return (CR), line feed (LF), and the combinations CR+LF and LF+CR] is to show their color values, which are cued in the legend at the bottom (blue=CR, green=LF, cyan=CR+LF, magenta=LF+CR). In addition , the end of the file is denoted with a red End-of-File (EOF) mark. Sometimes it is very useful to know exactly what delimiter combination your word processors use, so you can duplicate it when you edit with CF. You can toggle the colored delimiter symbols off and on with Alt-Minus or the gray minus key. (This is also covered in a help screen you can get by pressing Alt-H or F1.) _____ Information Area. . . The name of the file being viewed is shown in the lower left prompt area. The lower right prompt area shows the ASCII value of the character at the cursor (decimal and hex), the position of that character in the file (starting with 1), the file record the cursor is in, and the position of the cursor within the record (called "Column", which for a long record is not necessarily the same as the screen column). This information display may be toggled off and on with Alt-Plus or the gray plus key. _____ Line Wrapping. . . The default display mode is line wrapping, where any record longer than 80 characters is wrapped to the next screen line, so that all text is visible. This mode can be toggled (see the Wr/NW at upper right for current status) with Alt-W. In the NoWrap mode, each record longer than 80 characters simply extends off the screen to the right, but is accessible for viewing by putting the cursor on it and [Ctrl- or Shift-] Rt Arrow-ing (see below) to any place on the line. _____ Cursor Movement. . . The arrow keys, either on the cursor keypad or numeric keypad, move the cursor one line up or down and one character left or right. Ctrl- Left/Rt Arrow move left or right one word at a time, and Shift-Left/Rt Arrow and Home/End move to the beginning or end of the line, as in PCWrite. PgDn/PgUp moves the display up or down 20 screen lines, and leaves the cursor on the same video line. Ctrl-PgUp/PgDn moves the display by 200 screen lines (10 video pages) for fast paging through a file. Shift- Up/Down Arrow moves to the top/bottom of the current page. Alt-B/E moves to the Beginning/End of the file contents in memory. For very LONG files, exceeding available memory, the editor loads only as much as fits. When you get to the end of that section (i.e., the current "file contents in memory" referred to above), the next operation that asks for another page or line causes the editor to load in the next section, remembering the file position of the start of the previous section so it can backtrack if you want. (It actually loads the next section with some overlap to the previous section, so that a little bit of backtracking does not result in reloading the whole previous section.) This "heel-and-toe" sequential loading is limited to 50 sections. _____ Find a String. . . Want to look for a particular word or string of characters? The key combination Alt-F (for "Find") opens up a data window at the bottom for you to enter a short string. After you press Enter, CF will find the first appearance of the string from the current cusor position, and put the cursor on it. Alt-X (for "neXt") finds the next appearance, and can be used repeatedly until the string no longer appears, which is signalled at the bottom of the screen. The search process starts at the cursor location and goes, if necessary, to the end of the current file contents in memory. CMFiler -- Chapter 2 2-2 If the file is long and is being viewed by the editor module in sections as discussed above, only the CURRENT section is available to the Find operator. The search is case-insensitive. _____ Leading and Trailing Blanks in the Data Window. . . The data entry routine truncates leading and trailing blanks, but blanks may be included as leading or trailing characters by enclosing the string at either or both ends with quotes ("). Suppose, for example, you wanted to find all of the appearances in a file of the word "mark", but not "remark". Press Alt-F and, in the data entry window enter: Find string: >" mark <. This works for the replace string as well. _____ Editing a File. . . Exit view mode with either Esc or Enter. (Note that any tags in the source panel are still there.) Now you are ready to edit! Position the cursor over a file that you have an extra copy of somewhere, and press E (for Edit, obviously!). CF again loads the selected file, but this time with an internal "switch" set which tells the editor module to support editing. (Or, in View mode, press Alt-S, for "Switch to edit".) _____ Edit Mode Limitations. . . CF permits edit mode only if the file fits all at once into available memory, has fewer than 16,380 records, and (in NoWrap mode) has no record longer than 8190 bytes. CF will revert to view mode if these conditions are not all satisfied. If you have a lot of memory tied up in resident programs or RAM disk/cache, then you may not be able to edit extremely large files. Chances are, however, that this will never be a practical limitation. _____ Typeover vs Insert. . . Look at the small reverse video box in the upper right corner of the screen. "T/O" or "Ins", then CF is in edit mode. Toggle between typeover (T/O) and insert (Ins) modes with the Insert key. Typing action is just like any word processor. In typeover mode, the Bksp key does not pull the text left. This is to avoid unintentionally shortening the file when editing length-sensitive files, such as .COM and .EXE files. CMFiler -- Chapter 2 2-3 _____ Editing a Line. . . You operate on a line at a time, and the "normal" editing keys work -- i.e. Bksp, Del, Tab, Shift-Tab, the unmodified and modified arrow keys discussed above, and any ASCII-code keys. To create a new line, just Shift-Arrow to the beginning or end of the current line, depending on whether you want the new line above or below the current one, and hit Enter. This inserts the default delimiter combination, CR+LF, into the text to set up a new line void of text, but ready for you to start typing. The combination Ctrl-Enter gives you a menu screen from which you may select a different record delimiter. Join two lines by deleting the record delimiter at the end of the first line to be joined. Delete a line with Ctrl-Y ("Yank"). Delete from the cursor to the end of the line with Ctrl-D. Delete a word and its associated whitespace with Ctrl-T. _____ More on Record Delimiters. . . On CGA/EGA/VGA monitors, the record delimiter appears as a single colored "blank" character at the end of the line, whether it is actually two characters (eg., CR+LF) or one (eg., LF). It may be deleted to join two lines, but not over-struck -- it always pushes right, even when you are in typeover mode. The red "End-of-File" (EOF) marker is not actually part of your file, but rather is only a visual aid for you to see where the text ends. When the cursor is on the EOF marker, the "byte number" in the legend corresponds to the number of the next character, if you were to type one. The EOF marker also always pushes right, and cannot be deleted. The height of the cursor shows the status of the "Caps Lock" switch. _____ Alt- Keypad and Alt-N. . . Any ASCII code from 1 through 255 can be entered from the numeric keypad using the Alt- key modifier. A special combination is provided for ASCII zero ("NULL"), since Alt-Zero is not recognized by any keyboard drivers I have seen. It is Alt-N (for "Null"). _____ Block Operations. . .or the REAL Power of CF's Editor. . . All the block operations -- there are six -- are keyed to Alt-key combinations, and they are all intuitive (sort of). They are: Alt-{ Mark, Yank (delete), moVe, Copy, Print and Output }. CMFiler -- Chapter 2 2-4 _____ Marking a Block, and the Copy Buffer. . . You may also manipulate blocks of records. First mark a block by putting the cursor on the first (or last) record of the block you want to do something with, press Alt-M (for "Mark"), move down (or up) with arrows, PgDn/Up, etc., and mark the last (or first) record of the block, again with Alt-M. The marked text is written into a copy buffer for later use. If you made a mistake, a third press of Alt-M clears the marks, but leaves the copy buffer intact. The contents of this copy buffer REMAIN AVAILABLE FOR MULTIPLE USE UNTIL A NEW BLOCK IS MARKED. You may exit the editor back to the main module, and edit another file, and because the editor copy buffer is a dedicated chunk of RAM in the main and editor modules, the buffer is still intact. Just copy it into the next file with Alt-C. When you are marking a block, note that the information box at the bottom left of the screen expands to show you the attributes of the marked block -- the number of the first and last records marked, and the number of bytes in the painted area. There is an arbitrary 32 KB limit on the copy buffer. The upper right-hand information box shows "Blk" instead of "T/O" or "Ins", meaning that normal editing is not permitted while you have a block marked. _____ Delete, Copy, Move. . . Delete the block with Alt-Y ("Yank"). Or put the cursor in an unpainted area of the file, and copy the block into that area, just ahead of the line where you put the cursor, by pressing Alt-C ("Copy"). Or move it with Alt-V ("moVe"). As noted above, the block previously "marked" into the copy buffer is available for multiple use. Just put the cursor where you want the block to be copied and hit Alt-C again. _____ Restoring from Inadvertent Block Deletion. . . If you just deleted a block in error, put the cursor where you want to restore it, and press Alt-C to copy the buffer back into the file. _____ Sending a Block of Text to the Line Printer. . . Print the copy buffer to line printer 1 (the parallel port) with Alt-P ("Print"). After printing, if you want a form feed, press Ctrl-F ("Form feed" -- note the use of Ctrl- vice Alt- as the modifier key, since Alt-F was already used for "Find"). CMFiler -- Chapter 2 2-5 . . .or to a File. . . Finally, output the copy buffer to a file in the same path as the file being edited by pressing Alt-O (letter "O" for "Output"). A window opens at the bottom for typing the name of the file for CF to create (if it doesn't already exist) or append to if it does. (The file will be created or opened in the current directory on the default drive. Therefore the characters ":" and "\" will not be recognized.) _____ Replace and Global replace. . . In addition to the Alt-F "find" feature, there is an Alt-R "replace" and an Alt-G "global replace" feature. Just press Alt-R or Alt-G and enter the find and replace strings when prompted. (If you see a mistake in the find string while you are typing the replace string, just arrow back up a line and reedit it.) For Alt-R, CF will find the first match and ask you to confirm the replacement. It continues finding and requesting confirmation until you press Q (for "quit replacing"). Alt-X reactivates either the find or replace routine, whichever was used last. Alt-G replaces all appearances of the find string with no confirmation. It may be terminated with any key press. When global replace was thus terminated, Alt-X reactivates the confirmatory replace, not the global replace. _____ Leaving Edit Mode. . . After editing is complete, press Esc. The first prompt you get asks whether you want to save this edit (y/n), or go back to the editor (Esc). (If you had hit the Esc key by mistake, hit it again to return to where you were.) In some cases you botched the file up so bad you don't want to save it, but most of the time you do. Press Y or Enter to accept the default offering, or N to not save the edit. The second prompt wants to know if you wish to reuse the original file's date/time stamp for the editied file. N (the default offering) or Enter results in the file's date/time stamp being updated to the current system values, Y preserves the original values. The final prompt wants to know if you want to save the original, pre-edit version of the file as "*.BKP" (an arbitrary extension designator I picked to show the file as a "BacKuP" from edit mode, different from the form of the backup extension assigned by the backup command B from the main module.) If you press N or Enter, the edited version will simply overwrite the original. If you press Y, then the previous backup file with the same name and extension ".BKP", if there is one, will be deleted, the "current" original file will be renamed with the ".BKP" extension, and the now-edited version will be saved under the CMFiler -- Chapter 2 2-6 original name. If CF runs out of file space, it will ask you to put a NEW disk into drive A to save the edited version. The defaults for these three exit questions (Y, N, and N) have been selected so that most users will be able to exit the editor with Esc and three strokes of the Enter key for most of the edits they will do. _____ Backup File Protection. . . A small point of backup file protection. If, in the process of saving the original version of the edited file, CF encounters a file with the same name and the ".BKP" extension, it will simply overwrite it, UNLESS it is assigned the read-only attribute and the original to be renamed and saved is not. In this case CF will give you the option of saving the read-only file. _____ Creating a New File with the Editor. . . A new file may be created from the main module by pressing the letter F ("new File") and entering a name for the new file in the data entry line. The new file will appear in the directory from which the F command was issued. _____ Help. . . A one-page help screen may be summoned on-line at any time in the editor with the command F1 or Alt-H, and exited with any keystroke. CMFiler -- Chapter 2 2-7 ******************************* * * * CMFiler -- Version 5.35 * * * ******************************* TUTORIAL -- Chapter 3: The TREE Functions: CF lets you you view and operate on the subdirectory structure of your disk in the format of a "tree", so-called because that is what it looks like, with each subdirectory being a "limb" for the finer "branches" in its substructure. This feature is invoked with the command Shift-Tree. The command conventions in the tree module are the same as you have encountered in the main screen, except on a much smaller scale. The path(s) on entry are preserved from the main screen, and the selected subdirectory structure in the source panel is highlighted as a block. This source block may be copied, moved or (with GREAT CAUTION) deleted. A fast machine can wipe out a lot of files in a big hurry, and because of this I have added a second confirmation of any delete operation that involves file destruction. _____ The Display. . . If you entered the tree feature with both panels open, you see that the source/target panel relationship is preserved, and the paths displayed at the top and indicated by the cursor highlights in the tree structure itself are as existed from the main screen. The structure under the cursor in the source panel, namely the selected directory and all its files and subdirectories and their files, is shown as a block with red background in color mode, while the current directory selected in the target path is shown by its name highlighted with a black background. If you entered the tree module with the right-hand panel closed, you may open it the same way as you would from the main screen -- right arrow, then press a drive letter at the prompt. Line 1 at the top of the screen gives the status of two display enhancement switches. The "hide" and "compare" switches are passed from the main module, and have the same function. When the hide switch is on (^Hide=Y), subdirectories with the hidden attribute set are masked (i.e., not displayed). When the compare switch is on (^Comp=Y), any match in the target panel to the currently selected path in the source panel will be highlighted in high-intensity yellow, similar to the highlighting of file matches in the main screen. The hide and compare switches may be toggled using Ctrl-H and Ctrl-C (shown as ^H and ^C); their states are transmitted back to the main module on return. The "Goto" string also appears on the top line when the Goto file or Goto directory command is given (G or Alt-G). More on that later. Information about the selected structures is contained in lines 23 and 24 at the bottom of the screen. In each panel, there are two pairs of numbers, one pair for the amount of DISK SPACE used by the files in the structure, a second pair for the NUMBER of files in the structure. The first number in each pair desribes the files in the IMMEDIATE directory that the cursor is on (think of this as the "root" of the structure), and the second number in each pair describes the grand total charactertics of the file ensemble in the ENTIRE structure. The structure in the source panel is highlighted differently because this is the structure you will be operating on. Cursor movement is much the same in the tree display as in the main screen. Left/right arrows switch panels, up/down arrows move one line up and down the tree, PgUp/Dn move to the top/bottom of the panel and then 20 lines, Home/End move to the very top or bottom of the tree, and P (for "Parent") moves the cursor up to the directory's parent. Two additional cursor moves are Shift-Up/Dn Arrow, which moves the cursor up or down one directory in the same level; and Shift-Lf/Rt Arrow, which moves the cursor directly across to the match if you are in compare mode and have a path in the target matching the path of the currently selected structure in the source (same feature as in main module). Changing disks or drives (N), refreshing the panel from the disk (Shift-R), renaming subdirectories (R), setting the hide attribute for a subdirectory (2), and toggling the hide switch (Ctrl-Hide) all work the same as from the main screen of CF, except that no wild cards are permitted in the rename function. _____ Copying structures. . . If you, as I, never previously thought or visualized much about the structure of the data on your hard disk, and never thought in terms of moving around big blocks, the conventions about to be described will take a little getting used to. However, you will come to find these operations a great convenience. Select in the TARGET panel a path under which you want to replicate a substructure from the source panel. Pick a small structure in the source panel for starters. Now picture the source block highlighted in red (if you're in color -- in reverse video if monochrome) appearing UNDER the subdirectory in the black background in the target panel. Press C. The structure selected in the source panel is reproduced, subdirectory-by-subdirectory, file-by-file, under the target path. (One prohibition -- CF does not permit copying a structure onto itself. That is, if you have the same drive selected in both panels, a structure in CMFiler -- Chapter 3 3-2 the source and its HOST (the subdirectory it originates from) in the target, the command C will be ignored.) This copy operation is good for backing up major structures hard disk-to-hard disk or hard disk-to-floppy. Once a backup structure exists on another medium, you may KEEP it up to date the same way. Just remember to put the cursor in the target panel to the HOST directory of the structure you are backing up. Updating is possible because the file copying and protection convention used in the tree module is the same as that employed in the main program of CF. Namely: o Files encountered in the target path with the same date/time stamp are presumed identical, and not rewritten, unless the "file overcopy" switch is on. As in the main module, it is toggled by the command Shift-O, and its current state is displayed on the bottom line of the screen whenever you press the Shift- key (either "Overcopy=N" or "...=Y".) As with the "hide" and "compare" switches, the current state of the "overcopy" switch is passed between the main and tree modules. o Files of the same name encountered in the target that are newer than the source, or that are read-only and the source is not, require confirmation to be overwritten. o Files of zero length in the source path are not allowed to overwrite files in the target, newer OR older, without confirmation. Copying in progress may be terminated using Esc. Any errors during file copying automatically cause immediate termination of the tree copy operation, with a caution note to check over the files in the new structure. Check the file whose copying was in process first. The copy function tries to anticipate the disk space required in the target for the structure being copied, and will proceed without delay if it finds there is enough free space on the target disk to assure the completeness of the copy. It does not attempt to check the target path for possible file duplications with the source block and take for credit as "available space" the space occupied by files which will be overwritten. If it senses not enough space to CLEANLY copy the whole structure, it will alert you to the possibility of an incomplete copy, and ask for confirmation to proceed anyway. Then, as the copy operation proceeds, it checks disk free space before EACH file is copied. If there is insufficient space for THAT file, it tells you so, and asks whether you want to try the next file. The answer "n" terminates the operation. When backing up structures on your hard disk using the tree structure copy function, if the backup floppy is at all tightly packed, you will get this advisory message. If you know there is a lot of file duplication between the source structure and the backup floppy, you may proceed with the copy operation with confidence that all the files will be properly updated. CMFiler -- Chapter 3 3-3 A final word on the copy function, and the move function discussed below. The original cursor position in the TARGET panel, which specified the target path for the operation, is reset after the copy or move operation to show the TOP LINE of the new structure just created or moved, so that you can see that the copy or move actually took place and check using the information at the bottom of the screen that all the files were reproduced or moved. However, on the next keystroke, the target cursor is reset again to its ORIGINAL position. _____ The "Copy Into" Function. . . As seen above, the copy function replicates, as a structure UNDER the target directory, the source block. The structure has the same "name" in both cases, meaning that the top line of the block in the source panel is the same as the top line of the replicated structure in the target panel. Another way to view this is that the subdirectory which serves as the "root" of both structures has the same name. While this seems a convenient way to copy structures between two large mass storage devices, as it forces a uniform convention on the naming and construction of the structures themselves, it may not always be the most convenient way to backup structures from a large mass storage device to a smaller one. This sounds very cryptic, so let me try an example. Suppose one of the major structures in your hard disk is a directory under the root, containing all your files pertaining to your word processor. Let's call this directory WORDS. In it are all the program support files (the editor, the printer, the configuration files, etc.), and two subdirectories, NOTES and LETTERS. If you were to copy the structure with WORDS as its "root" to a virgin floppy, the screen would end up looking like this: C:\ A:\ |---ANYOLD.DIR ( +---WORDS |---WORDS ) . . . . ( |---LETTERS | |---LETTERS ). . . ( +---NOTES | +---NOTES ) +---ZLAST.DIR But suppose you plan to dedicate this floppy exclusively to the backing up of the files in the WORDS structure, and so you really wanted to put the word processor program and its support files INTO the root directory of the disk in A:, and have the LETTERS and NOTES be directories of the ROOT, not of a directory WORD. That is, you want not to create the unnecessary layer of a directory called WORDS, but you want the A: disk tree to look like this: A:\ <Where the programs and support are here in the root> |---LETTERS +---NOTES CMFiler -- Chapter 3 3-4 This is where the command "Copy Into" does the job. Just press the letter I instead of C, and the contents of the structure in the source panel block are copied INTO the target directory, instead of being replicated as a new, complete substructure. _____ Moving structures. . . In much the same way, structures may be moved within the same disk with the commands Shift-C (which replicates the structure entirely, similar to Copy) and Shift-I (which moves the structure INTO the target, like Copy Into). The condition for moving is that the same disk is selected in both panels, and the target path is not currently the host of the structure selected in the source panel. Since these operations use the DOS rename service, no copying of any file data itself is performed, just modifications to the directory tables, and so this is a QUICK way of doing major reoganizations of your hard disk. "Move" (Shift-C) and "move into" (Shift-I) default to straight "copy" and "copy into" if different disks are selected in the source and target panels. Moving may be terminated with Esc. _____ Copying Just the Files. . . The command J (for Just files) works somewhat like the Into command, but copies just the files in the source subdirectory into the target path, and not the subdirectories and their files and subdirectories, etc. _____ Copying Just the Directory Array. . . The command Alt-C is similar to C, but copies just the skeleton of the structure, the directory array and no files, under the target path. Alt-I, similar to I, copies just the directory structure INTO the target path. _____ Deleting Structures. . . This is the scariest of all the tree functions, because a couple of false keys and a fast hard disk and you're destroying files REAL fast. For this reason, I have added a second confirmation step which warns you how many files are about to be destroyed before it starts, and, for hard disks, have used the same "soft" delete convention for the operator D as discussed in Chapter 1 on the delete function in the main module. (If the structure selected consists entirely of empty subdirectories, CF CMFiler -- Chapter 3 3-5 doesn't bother asking for the second confirmation, since directories are a whole lot easier to re-create than files.) Thus, when file destruction is involved, three keystrokes are required to delete a structure -- D, Y, and Y -- and, for a hard disk, the files deleted will reappear in the CF_TRASH.CAN directory. As in the main module, the alternative "hard" delete function is Ctrl-D. Esc terminates tree deletion in progress. CF deletes ALL the files in each subdirectory shown in the tree structure -- hidden and read-only, as well as normal. The move and delete operations use a routine to remove the (assumed empty) tree structure in the cursor block in the source panel after all the files have been moved or deleted. If there is a hidden subdirectory in this structure, and the hide switch is set to "Yes", however, it will not be seen by the file moving or file deleting routines, as well as the directory removal routine, and a strange-looking error message will be returned, namely "Access denied" during directory removal. This is classic DOSese, at least most of the time, for "there is something still in there." Toggle the hide switch with Ctrl-H and reexamine the remnants of the structure you tried to delete. To save you time, CF does not reread the tree from the disk after a piece has been deleted, but rather marks the image it made in memory of the tree structure to note the part has been deleted and should not be used in drawing the tree. As a consequence, the statistics -- files and KB used by the directories above the deleted portion, will not be accurate. After several deletes, you can refresh the tree from disk with Shift-R (Refresh). _____ Delete Just the Files. . . The companion delete operation to the "copy Just files" command is Alt-D -- delete just the files in the source subdirectory. This is a "hard" delete. _____ Show the File List. . . The command S, for "Show files", is the way to get a look at the file names in a subdirectory without leaving the tree environment. This command opens a window in the target panel showing the first 16 files in the directory at the cursor in the source panel. You may continue to scroll up are down through the source panel as before, but now the file window changes as you do to show the contents of the current directory. You may do any other operations that involve only the source window, such as toggle the hide mode, make a new directory, delete a portion of the CMFiler -- Chapter 3 3-6 tree, even get a new drive. Two-panel operations such as copy and move are blocked in this mode by the presence of the "Show files" window. To see more than the first 16 files, arrow across with the left or right arrow to the file window and scroll up and down using the up/down arrows, PgUp/PgDn, Home and End. View or edit the file with Enter or E, as in the main module. Move between the tree and its file list with the right or left arrow keys. To return to the main module and perform an operation on a file in the file list, press Shift-Enter with the cursor on that filename. CF immediately returns to the main module, to the directory selected, and places the cursor on that file, ready for you to edit, view, execute, copy, etc. Leave the "Show files" mode with Esc or S from either panel. _____ Find (Goto) a File. . . One of the most powerful functions in the tree arsenal is the filename finder. There are lots of file-finding utilities around, but most of them tell you where a file is by giving you its path which you have to type into a DOS "change directory" command. Cumbersome. CMFiler offers a file finder which gives you an instant visual cue to the directory(ies) containing the file you are looking for. Simply press G (for "Goto file", just as in the main module). A data window opens at the bottom for you to type the name of the file to search on. It supports the "?" and "*" wildcards. When you type the first letter, the "Show files" list opens in the opposite panel, and both the tree display and file list dynamically adjust to show current matches. Keep typing until the matches have been narrowed down as far as you need to go, and press Enter or Esc. Assuming there is at least one file that fits that specification, note that several things have happened: o At least one directory name in the tree is highlighted; o The cursor has automatically repositioned to the topmost highlighted directory; and o All the file matches are listed in alphabetical order at the top of the window, and are also highlighted. If you have a long tree structure with subdirectories out of view off the bottom of the panel, you may not see all of the highlighted subdirectories containing file matches. If there are some subdirectories in the tree containing matches but which are off the screen above of below, a flashing "More" will appear at the top or bottom in the tree display. The cursor movement in the "Goto file" mode that lets you quickly position up or down to the next directory containing a file match CMFiler -- Chapter 3 3-7 is Shift-Up/Down Arrow. Use Shift-Up/Down Arrow to see all the directories with a match. Otherwise navigation and services are the same as Show files mode. If there are match files out of view above or below the file window, a flashing "More" will appear at the top or bottom of the file window frame. Quit "Goto file" mode with Esc, G or Alt-G. _____ Goto a Directory. . . There is also a quick way to navigate to a subdirectory anywhere in the tree that, like the "Goto file" command, mimics a command in the main module. It is Alt-G, and it behaves similarly to G above, except that the file list is not opened in the other panel, and the tree display is changed dynamically to highlight the directory name matches and position on the topmost match. Type the name of the directory you are looking for, and when it has been singled out to your satisfaction, type Enter or Esc. Matches are highlighted in the target tree, if one is shown. Shift-Up/Down Arrow to the next match up or down; otherwise navigation and services are normal. Quit "Goto directory" mode with Esc, G or Alt-G. _____ Find Text. . . Another powerful operation in CMFiler's tree services, to complement the filename finder, is a file text finder. Press Shift-F (Find text). Enter the text to be found (the search is case-insensitive), and then enter up to eight filenames describing the types of files you want included in the search, separated by + signs. The pipe symbol (|, ASCII 124) placed in front of a filename means "do not include this type". So, for example, the entry: CMFILER.*+|*.COM+|*.OVY+*.TXT would result in a search of all files with the name CMFILER except CMFILER.COM and CMFILER.OVY, plus all files with the extension .TXT. CF's guess at this point on what part of the disk to search is that you wanted to look only in the selected portion of the tree -- the structure at and below the cursor. Just to be sure, it asks for confirmation, and will allow you to extend the search to the whole disk if you wish. An option for the text search string is the character "*", which means "accept any text". This is useful, for example, if you wanted to see all the files of several different descriptions in the tree, but didn't want to do each at a time using the filename finder (which only CMFiler -- Chapter 3 3-8 supports one entry), and didn't care what they contained. Suppose you want to see all the executable files on your disk. Just press Shift-F, enter * as the text, and *.COM+*.EXE+*.BAT as the names to search on. _____ Viewing or Editing Files. . . The editor is accessible directly from the tree module. In either the Show files or Goto file mode, with the cursor in the file list window on a file name, press Enter to view or E to Edit the file. _____ Deleting Files from the File List. . . Another feature in the Show files and Goto file modes that speeds disk cleanup is individual file deletion while the cursor is in the file list. The following commands are available, which mimic commands in the main file services module: Tag (or spacebar), which toggles the tag on an individual file; tagAll, which clears or sets all tags; soft Delete file(s) to CF_TRASH.CAN; and Ctrl-D hard delete file(s) off the disk. This feature gives you a more macroscopic view of your disk while you are cleaning it up. _____ Print a Hard Copy of the Tree or Found Files. . . Except in the Goto file and Find text modes, the command Alt-L (same syntax as in the main module) prints a copy of the tree structure to the printer. In Goto file or Find text mode, however, Alt-L prints an alphabetical listing, organized by directory, of all the files identified by the preceding search. The date, time, disk volume and search parameters are all printed at the top of listing. _____ Precaution Regarding CF_TRASH.CAN. . . The directory CF_TRASH.CAN is not permitted as the source for a copy or move operation. Since this directory contains files whose date/time stamps were reset to the current date and time when they were "soft deleted", they will generally APPEAR to be newer than more current files of the same name elsewhere on the disk. Thus indiscrimant copying or moving of them may overwrite later files. Files in this directory may ONLY be moved/copied from the main module, and only after confirmation. CMFiler -- Chapter 3 3-9 _____ Help. . . A one-page help summary may be summoned on-line at any time within the tree module with the command F1 or H. _____ Leaving the Tree Functions. . . There are three ways to leave the tree display. Enter goes back to the main program display, with the path(s) for the left (and right, if open) panel(s) as selected on the respective trees. Esc goes back to the main program with the path(s) set as they were on entry. And finally, Alt-Q has the same convention as in the main program -- quit CF altogether, with default drive and current directory as selected in the tree source panel. CMFiler -- Chapter 3 3-10 ******************************* * * * CMFiler -- Version 5.35 * * * ******************************* TUTORIAL -- Chapter 4: Launching User Applications: So far, you have seen the features that make CF useful for file and directory management -- neatness of file display, flexibility in manipulating directories and files, transparency of operation, and even the ability to edit files without leaving the environment of CF. What really makes CF useful as an OPERATING environment, though, is its ability to execute user applications with an economy of keystrokes. Running programs in the DOS environment is one of the more cumbersome and confusing aspects of this operating system, and therefore, by its nature, this chapter is not terribly straightforward. I will make it as simple as I know how. _____ Terminology: User Application as "Child" Program. . . A "user application" is nothing more than a "child" program, executed by the DOS operating system under the command of the "parent" program, which stays resident and waits for the "child" program to finish. When you ran CF from the DOS system prompt, it was as a "child" of the DOS COMMAND.COM command processor. Some word processors permit you to "shell" to DOS, leaving the word processor program code resident in memory. What the word processor program is actually doing is running the DOS COMMAND.COM command processor as a child. From this DOS "shell", you could run yet another program as a child. The more layers of child programs you have at any time, the more RAM you eat up for the currently running program with the resident code of generations of parents waiting to take back over. _____ Resident Footprint of CF. . . If you use your computer for more than just one task, therefore, you may find CF useful as an "inner shell" of your operating environment. You may let all 99 KB stay resident (the CF.COM kernel plus the CF.OVY overlay) while the child is running, or if you are memory-limited you may force CF to give back to DOS for allocation to the child all but 19 KB for the CF.COM kernel. This option is exercised by pressing K (for "Kernel"), and then pressing either L or S at the prompt (for "Large" or "Small"). "Large" is the default in a virgin copy of CF.COM. The default setting embedded in the CF.COM file on disk gets updated to the current value anytime you update the user-defined F1-F9 applications table with the command Shift-F10 - Ctrl-Enter. There is a tradeoff here. The large kernel option ties up more RAM that could be used by the child if it is a humongous program, but the return to the CF environment after it finishes is instantaneous. The small kernel option is good for freeing the maximum amount of RAM for the child, but there is a delay in returning to CF while the resident kernel reloads the overlay. You be the judge. The best thing is that you can decide before each launch, if you want, at the cost of only two keystrokes! _____ "Shelling" to DOS. . . You may "shell" to DOS -- that is, execute the DOS command processor -- any time you want from the main screen just by pressing S. A prompt will tell you to return to CF when you are done by entering the DOS "exit" command. This is the most elemental child program provided for in CF. _____ Review of DOS Command Line Structure. . . Before talking about how CF launches applications, let's review how it's done from the DOS command processor. Say you are in the root of the C drive, and you want to start your PCWrite word processor, which is named ED.EXE and is in a directory called PCW off the root. Further, let's say you want ED.EXE to edit a file called USER.LST in a subdirectory of PCW called DATA. At the C:\> prompt you could type: C:\>PCW\ED.EXE C:\PCW\DATA\USER.LST What this command tells DOS is: 1)leaving C as the default drive and the root \ as the current directory, go to directory \PCW, find and execute ED.EXE, and pass the string "C:\PCW\DATA\USER.LST" along to it as a "command tail", so it knows what you want it to do. (The "command tail" is nothing more than everything in the DOS command line after the program specification (in this case PCW\ED.EXE).) C:\>PCW\ED.EXE C:\PCW\DATA\USER.LST |<-prog->| |<----command----->| | spec | | tail | If you have typed a lot of DOS command lines, you know how tedious they can become, particularly if there is more than one parameter in the command tail after the program specification. But you know that most of the time, the one or more parameters in the command tail are filenames or CMFiler -- Chapter 4 4-2 file specifications (with full path specifications in front of them), and sometimes there are parameters the program will use to configure what it does -- command line options. The ensuing discussion may be simpler if you think about each step in launching an application from CF as having to do with constructing either the program specification (the first argument in the command line, telling what program you want to launch), or the command tail (everything else, which the launched program needs to know to do its thing). _____ Launching a Program from the Main Screen. . . You can run any "executable" (.COM, .EXE or .BAT) file from CF, as a child program, anytime you want, from the main screen. There are several ways to do it: _____ Immediate Execution. . . This is the quickest way. Just position the cursor on an executable file entry on the screen and press Q (for "Quick execute"). This is ideal if the program is located in the same directory as any files it might look for, and it does not need a command tail to tell it what files to operate on or what optional switches to set. This is just like typing in the name of the program at the DOS command line, once you are selected to the directory containing the program. _____ Execution with Command Tail. . . However, as discussed above many programs expect data in the command tail, such as the name of a file to operate on, and CF has provided several ways of constructing the DOS command line. The simplest is this: First, position the cursor on the file you want to execute and press X (for "eXecute"). This constructs the "program specification" for the DOS command line. A prompt message will tell you this file is ready for execution, its path and name put into a special buffer in RAM, lined up and waiting for the launch command from you to commence execution as soon as you select the drive and directory the program will want as its default path to the files it will operate on. Select the default path the program will want in either panel, and leave that panel set as the source panel, and then press Alt-X. A data entry window opens at the bottom, in which you may enter a command tail for the program's use. Enter the command tail data your application expects, and hit Enter to run. CMFiler -- Chapter 4 4-3 _____ Execution with a Single File Name in the Command Tail. . . The simplest case of the command tail is a single file name. CF offers a shorthand way of running a program with a one-filename argument as the command tail. Put the cursor on the name of the program file you want to run and press X as before. The program is ready to run. Now find the directory containing the file you want this program to operate on, put the cursor on the filename, and press Ctrl-X. It's off and running, editing (or whatever other operation it's doing on) that file. Two keystrokes. Ctrl-X means "add the name of the file at the cursor to the command tail and execute immediately." It is a good idea to have the program file and its supporting files in the same directory as the "operand" files when you use this method of execution, unless the program is smart enough to locate its supporting files in another directory in the DOS path environment. _____ "Seeding" the Command Tail. . . In many cases, the above quick way to specify a one-filename command tail is not enough. You may find a need to put into the command tail the names of several files from what will be the default path when the program is executed, or the full specifications of several files not in that path on execution. In CF, there are shorthand ways of "seeding" the command tail window with file specifications and filenames. These may be used either before or after readying the program file for eXecution with X. o To seed the command tail with the FULL specification (path PLUS name) of a file on which you want the program to operate, put the cursor on the filename and press Alt-C (the C in this case is a mnemonic for "build Command tail"). The information window at the bottom will show you the command tail in its current state. This procedure may be repeated to build a command tail as long as there is room in the command tail buffer. The command tail is limited to 125 characters. o Just before pressing Alt-X to show the command tail window for final pre-launch editing, you may Alt-Tag one of more files in the directory you have set up as the program's default path. These file names, WITHOUT paths specifications, will all appear in the command tail in the order they were Alt-Tagged. Now press Alt-X to open the data window with the seeded command tail. Once you have edited the command tail the way you want it, hit Enter, and the program is off and running. After the launched program finishes and returns control to CF, its file specification stays in the CMFiler -- Chapter 4 4-4 "execute" buffer until you ready another executable file with X, so you may perform multiple operations of the same program just by seeding the command tail again as above, and pressing Alt-X again. As a further time-saving feature, you may recall the last command tail by pressing the up arrow or PgUp while in the command tail entry field. Once you get used to the above conventions, you will find that in many situations you don't need to edit the seeded command tail, and the key sequence Alt-X-Enter seems cumbersome. For those cases I have included the option Shift-X. Use it after you have seeded the command tail using Alt-C and/or Alt-T, and avoid the extra Enter stroke. Its effect is to commence execution of the program with the as-seeded command tail, with no edit. _____ Changing the Command Tail "Seed" Delimiter. . . You probably noticed that there was always a space between multiple entries in the seeded command tails created using the Alt-C and Alt-T seeding operators by the procedures above. But what if your application looks for commas as the field delimiters for data in the command tail, instead of blanks? Just press Ctrl-Enter from the main screen to pick from three choices for default command tail field delimiters -- space, comma, and semicolon. _____ Customizing Your User Application File Specifications. . . Got a few pet applications that you run more than most? Save the aggravation of hunting them down and pressing Q or one of the X key sequences each time you run them. You can call them with just a touch of one of the function keys F1 through F9! To set this up, press Shift-F10. You will see a data entry screen that lets you specify up to nine executable file names in the entries "F1 = ", "F2 = ", etc., and an optional default command tail offering for each, labelled "F1 Comm Tail = ", etc. Further down the page, you will see places for similar entries for ZIP and UNZIP, and a bottom entry labelled "Password = ". (You may use this last entry to specify a password which must be entered to get back to the main screen from the screen-saver mode -- a handy way of blocking undesired access to your files.) In any "Fn = " data window, just type in the filename, including extension, of an executable file you use frequently, and, optionally, any frequently used command tail that you would like to show up as a default offering when you ready the file for execution. You do NOT need to include the path in the file specification if the file is on one of the paths listed in the DOS path environment (via a previous "path" command from the DOS system level) -- CF will hunt it down and update its internal record of where that file is, so it doesn't have to hunt the CMFiler -- Chapter 4 4-5 next time you call it. However, if you DO include a path specification, be sure it is complete (e.g., "C:\LETTERS\ED.EXE"). Once you have made all the entries you wish, press Ctrl-Enter to record the new entries and leave the F-key data entry screen. (Esc will abort the edit.) CF will then find and update the CF.CFG configuration data file to add the customized F-key information. (A caveat for DOS v2 users -- CF will find CF.CFG PROVIDED it is on a path in the DOS path environment, and you have kept it named the same as the kernel and overlay files). There are three ways to now use these F-key options: (This seems awfully confusing, but stay with me -- these features are what will really make CF useful to you!) o Press the F-key corresponding to an application you specified with the Shift-F10 operation. (This may be done from either the main screen OR the F-key information screen shown by pressing just F10.) You will get the message at the bottom that that executable file is readied for execution, just as though you had hunted it down and pressed X. Seed the command tail and set up the path desired in the source panel as before, and press Alt-X to get the command tail entry window, also as before. This time, though, if you had specified a default command tail offering for this F-key, it would appear in the command tail window, IN FRONT OF the seeded entries, if any. Edit the command tail if desired, and press Enter to start execution. o OR, if you know the command tail will be the way you want it, and you are bugged by the extra Enter keystroke to accept the seeded command tail, seed the command tail with Alt-C if you want, set up the source panel to the directory you want, Alt-Tag any files from this directory you want to appear in the command tail, and hit Shift-F-key. The application will run immediately with the seeded command tail, with the default F-key command tail offering between the Alt-C seeds and the Alt-T seeds. o OR, if you are just operating on one file, put the cursor on the name of that file and press a Ctrl-F-key for instant one-key execution. In this case, the F-key default command tail offering will appear in the command tail preceeding the name of the file the cursor was on. (This is the feature I use most.) (There is, in fact, a rule as to where the F-key default command tail offering gets placed during the construction of the command tail. It is inserted at the point that the F-key itself (or F-key modified by Shift- or Ctrl-) is pressed. The file names Alt-Tagged in the current directory always appear last. In an exotic case, for example, you could: (1) Alt-C a file spec, (2) press F1, (3) Alt-T a file name, and press Shift-X to execute with no edit of the command tail. The program assigned to the F1 key would run, with a command tail consisting of the file spec Alt-C'd in (1), the F1 default command tail offering, and the CMFiler -- Chapter 4 4-6 file name Alt-T'd in (3), all separated by the command tail delimiter character last selected from the main screen with Ctrl-Enter. The business above may seem cumbersome, but if you spend a lot of time typing the same old things in at the DOS command processor prompt, you will find it is worth the investment of time to figure out and use. _____ A Further Execution Option -- Instant ZIPping/UNZIPping. . . Phil Katz' PKZIP.EXE and PKUNZIP.EXE (c) have become the dominant file compression and decompression programs in the shareware market, so much so that I wrote a special explicit feature to employ them with just a few keystrokes. The commands which invoke these programs from the main menu are Z and U, respectively. CF can find these programs as long as you have not renamed them from PKZIP.EXE and PKUNZIP.EXE, and they are on one of the paths that you specified in a DOS path environment. If for some reason you want to rename them or put them on a path not listed in the DOS path environment, you may specify them explicitly via the Shift- F10 data screen. _____ ZIP a File. . . 1. Decide where you want the compressed file to go, and select that path in one of the panels. If you are updating an existing .ZIP file, Tag or Alt-Tag it while you are there. 2. Now switch to the other panel, and select the path to the files you want to compress. Tag them, Alt-Tag them in the order in which you want PKZIP to compress them if order is important to you. 3. Now then press Z. CF will show you a command tail at the bottom of the screen, in the PKZIP syntax (options first, then .ZIP file first, then list of files to be ZIPped.) Since the files to be ZIPped are in the current source path as set up by CF when you Alt-Tagged them, no explicit path is included for them. You may edit the command tail. Once you are satisfied with the command tail, press Enter. [In step 2 above, if you do not Tag or Alt-Tag any files for compression in the source path, CF assumes you want to ZIP them all, and places "*.*" in the file list argument of the PKZIP command tail.] [In step 1 above, if you do not Tag or Alt-Tag a target .ZIP file, CF assigns a default .ZIP file name for PKZIP to create, which is either: (1) the first Tagged or Alt-Tagged file in the source path from step 2, or CMFiler -- Chapter 4 4-7 (2) if no source files are Tagged or Alt-Tagged in step 2, the name of the file the cursor is on. (PKZIP attaches the default .ZIP extension).] [In step 3 above, if you know you don't have to edit the command tail, you can bypass the extra Enter keystroke to enter the command tail by pressing Shift-Z instead of Z.] _____ Now UNZIP a File. . . 1. Set up one panel with the target path for the UNZIPped files. 2. Switch to the other panel, select the path with the .ZIP file to be UNZIPped, and put the cursor on it. 3. Press U, edit the command tail if necessary, and press Enter. As with ZIPping above, if you know you don't have to edit the command tail, press Shift-U instead. The PKZIP/UNZIP utilities are available from most bulletin boards, or may be had for a $47 registration fee from PKWARE, Inc., 9025 N. Deerwood Drive, Brown Deer, WI 53223 (BBS 414-354-8670). _____ Tailoring CF for custom ZIP/UNZIP spec. . . If for some reason you want to specify an explicit path to PKZIP/PKUNZIP, you may include an explicit file specification using the Shift-F10 feature. Just follow the procedure and precautions under "Customizing Your Executable File Specifications" above, and operate on the "Compress = " and " Extract = " fields. If you are familiar with Phil Katz' option switch syntax and find yourself using one or more switches most of the time, you may enter standard options in the indicated fields ("Compress Options =" and " Extract Options = ") while you are at it. Once you are comfortable using the ZIP/UNZIP feature of CF, and you find you are not having to edit the ZIP/UNZIP command tail most times, you may start getting bugged about having to always hit Enter when you see the command tail displayed. There is an alternative! Just like with the tailored F-keys, hit Shift-Z/U for instant ZIPping/UNZIPping. CMFiler -- Chapter 4 4-8 _____ Using Other Compression Utilities. . . As it happens, some other compression utilities use the same command line construction as the PKWare utilities. Specifically, the ARJ utility by Jung and the LHA utility by Yoshizaki use command lines of the form: archiver options archivefile file1[,file2[,file3[,...]]] where archiver is the program spec, options is the collection of commands and switches to accomplish the desired operation, archivefile is the spec to the file which will contain the compressed data, and file1, file2, etc., are the specs to files to be compressed. The CF ZIP/UNZIP facility may be used to accomplish compression and extraction with either ARJ or LHA, and perhaps others as well. Here is how to do it with LHA as an example: o Make sure the file LHA.EXE is on one of the paths specified in your DOS environment, so that CF can find it. o In CF, press Shift-F10 to bring up the user-defined applications screen for editing, and down-arrow to the line "Compress = ". Type in LHA.EXE. Do the same for the line " Extract = ", since for this utility, unlike the PKWare set, the same program does both tasks. o For the most rudimentary compression and extraction options with LHA, the only parameter required for the "Compress Options = " line is the letter a, and for the " Extract Options =" line, the letter x. These parameters tell LHA whether to add (a) or extract (x). Type them in, and press Ctrl-Enter to save the new data. Compressing and extracting now work just the same as previously described for the PKWare utilities. To compress, optionally Tag ot Alt- Tag the archive file in one panel, go to the other panel, find the directory with the files to be compressed (the same path is permitted) and Tag or Alt-Tag them, press Z, edit the command tail if necessary and press Enter. To extract, set up one panel with the destination path for the extracted files (may be the same as the source), arrow across too the other panel, put the cursor on the file to be extracted and press U. Edit the command tail and press Enter. CMFiler -- Chapter 4 4-9 _____ Specifying a Password for Access from Screen Saver. . . At the very bottom of the Shift-F10 screen you see a data line for password. You may enter any combination of alphanumeric characters up to six letters. This password must be given to restore access to CF from screen saver mode. The password routine is case insensitive. CMFiler -- Chapter 4 4-10 ******************************* * * * CMFiler -- Version 5.35 * * * ******************************* REFERENCE -- Description by Operation: _________________________ DISK/DIRECTORY OPERATIONS: N -- New disk -- Select a new disk drive for the source panel, the one with the cursor. Must be used to announce disk media changes. In right-hand panel, Enter after N closes the panel. Enter -- Display subdirectory in source panel -- With the cursor on a subdirectory or the "<Parent>" line, changes to that subdirectory or parent in the source panel. Shift-Enter -- Display subdirectory in target panel -- Displays the subdirectory under the cursor in the target panel, and changes to it. P -- Display Parent directory in source panel -- Quick way of returning to the parent directory with the cursor positioned anywhere in the listing of a subdirectory. The same thing can be done with two strokes -- Home (to get to top line of the subdirectory listing, which is always "<PARENT>"), then Enter. Shift-P -- Display source directory's Parent directory in target panel -- Quick way of showing the parent of the current directory in the target panel and switching to it. \ -- Display root directory in source panel. Shift-\ -- Display root directory of source disk in target panel. Shift-* -- Display source directory in target panel. Alt-G, followed by a typed string -- Move cursor to ("Go to...") the directory described by that string. M -- Make subdirectory (Mkdir) -- With the cursor anywhere in the listing, pressing M opens a data window at the bottom of the screen for entering the name of a new subdirectory you want to make. CF checks the entry for validity; if invalid, the window simply clears and waits for another entry. A valid entry appears in the proper alphabetic position on the screen. D -- Delete -- With the cursor on a subdirectory and no files tagged, removes that subdirectory if it is empty ("void"). IF THE CURSOR IS ON A SUBDIRECTORY AND FILES ARE TAGGED, DELETES THE FILES. Alt-L -- Print directory Listing -- Prints a listing of the current directory if cursor in directory panel, and includes notes if cursor in one of the Notes modes (Shift-N or Ctrl-N). Shift-T -- Transfers control to the TREE module. Displays the disk(s) selected in the panels in their directory tree structures, and puts the cursor(s) on the structure(s) pointed to by the current path(s). __________________________ FILE OPERATIONS: G, followed by a typed string -- Move cursor to ("Go to...") file described by that string. Shift-Lf/Rt Arr -- Jump across to identical file name in opposite panel when highlighted in comparison mode. T or Space -- Tag file -- Applies or clears a "normal" tag to the file under the cursor (i.e., toggles the state of the tag). Window at bottom of screen shows number of files tagged. Alt-T or Alt-Space -- Alternate-Tag file -- Applies or clears an "alternate" (sometimes referred to as "append" because of its principal function) tag to a file. "Alt tags" are numbered (1-9, a-z) to show the order of application, for the order-critical operation of file concatenation, discussed below, and are white on red. A -- Tag All files -- Applies or clears normal tags to all files. Ctrl-A -- Toggle the state of All normal tags. Alt-M/E -- Tag all files with same naMe/Extension as file at cursor; does not reset tags already present. Alt-N -- Tag all files Newer than file at cursor. Alt-O -- Tag all files Older than file at cursor. Alt-D -- Tag all files same Date as file at cursor. Alt-P -- Tag same files in oPposite panel as tagged in source. (NOTE ON TAGS: Tags are aids for quickly performing multiple file operations, but are "volatile", and generally go away with any operation that changes or updates a panel. Tags are NOT applied in any way to the magnetic media.) CMFiler -- Operation Reference OpRef-2 C -- Copy -- Copies tagged files from source to target, or the one file at the cursor if none tagged. Does not bother overwrite identical files, asks for verification before overwriting newer files or read- only or hidden files, and protects against some cases of overwriting good files with files created in error. With files "Alt-Tagged", creates "concatenated" file in target with same name as first "Alt-Tagged" file, but extension ".APF". If insufficient room on target path, does not perform operation, and signals the user. Shift-C -- move -- Moves files from one subdirectory to another on the same disk. If conditions are not satisfied for moving (i.e., same disk, different directories), shifts back to copy mode. B -- Back up -- Copies tagged files (or file at cursor if none tagged) from source to source, assigning to each new file the extension ".~" (tilde) plus the first two letters of the original file's extension. This results in backup files with unique names unless two files differ only in the third letter of the extension (eg, ".BAK" and ".BAS" would both back-up to ".~BA"). With files "Alt-Tagged", creates file in source with the "backup" form of the "append" extension (ie, ".~AP"), and concatenates. If insufficient room on source path, does not perform operation, and signals user. D -- Delete -- Deletes all tagged files on source path. If no files are tagged, deletes only the file under the cursor. Treats normal tags and "Alt-Tags" the same. Requests confirmation before file destruction. On hard disks, this operation is a "soft" delete, in which files are redated to current date/time and moved to directory \CF_TRASH.CAN (created by CF). Thus good files inadvertently deleted are readily recoverable. On floppy drives, this operation is a "hard" delete, using the DOS delete file function. "Undeleting" is not available in the CF environment, but other utilities contain "undelete" facilities, but these are not always reliable. Ctrl-D -- "hard" Delete -- Uses DOS delete function regardless of disk type. Shift-F -- Freshen files -- "Freshens" the files in the source panel from the target. Useful in updating backup disks. If no files tagged in source, tags all in source, then tags in target all NEWER versions of same-named tagged source files and copies them to source. If any files were tagged in source, only these files are looked for in target, vice all files in source. R -- Rename file or directory -- Prints name of file at cursor, and opens window below it for new name, offering the current name as the "seed". Type/edit new name and press Enter. Or first arrow up and edit the current name field, for example to use the "*" wildcard. One use of "*" is permitted (either the name or extension). If used in the current name field, it must be followed in the new name field. Names are checked for legality before renaming is attempted. CMFiler -- Operation Reference OpRef-3 Alt-R -- copy with Rename -- Copies the one file at the cursor in the source panel to the target, after entry of new name in data window. Enter -- Display file -- With the cursor on a file, views that file. F -- make new File -- With the cursor anywhere in the listing, pressing F opens a data window at the bottom of the screen for entering the name of a new file to be created. Entry is checked for validity. If valid, control is transferred to the line editor for file creation and editing. 0, 1, 2, 3, 4 -- Toggle File Attribute -- Pressing the number 0 clears all attributes for any files tagged, or for the file under the cursor if none are tagged. 1 toggles the read-only attribute, 2 the hidden attribute, 3 the system attribute, and 4 the archive attribute. (Only the number keys at the top of the keyboard are active for setting file attributes. The numbers on the keypad are mapped to their corresponding cursor movement functions, even when the NUM LOCK is set. (The command syntax can be remembered as "1234=RHSA".) L -- print fiLe -- Put the file under the cursor into the queue for printing as a background process while in CF or any child of CF. (Printing is suspended during any DOS functions, such as disk read/write.) Up to five files may be thus queued. Shift-L displays the print queue. Ctrl-L clears the print queue. Ctrl-F while files are printing from the print queue sets an internal flag which causes a form feed to the printer at the end of the file most recently added to the print queue if the file itself does not have a form feed as its last character. (At times when the printer is not in use by CF, Ctrl-F sends a form feed immediately.) V -- Volume label -- Permits entry of a new volume label for the disk Shift-O -- set user Option switches -- Permits the resetting of six user- specified Yes/No option switches for 1) redefining the F1 key as Help, 2) redefining "D" as "hard" delete, 3) clearing the I/O buffer structure if found before write (eliminating inadvertent copying of stray data into sector slack space), 4) overcopying identical- appearing files during copy operations, 5) refreshing directory list on return from screen saver, 6) un-hiding the NARATIVE.CF notes file, and 7) selecting monitor type. Alt-F -- Change file date/time stamp. CMFiler -- Operation Reference OpRef-4 _________________________ FILE EDITING/VIEWING: Enter -- View a file -- When the cursor is placed over a file, Enter lets you view the file on the screen. In this mode, the lower right screen display gives information about the byte the cursor is on. Alt-H displays help screen. Alt-Plus and Alt-Minus toggle the bottom information display and the color-enhanced display of record delimiters (CR, LF, CR+LF, LF+CR). Esc or Enter exits View mode. E -- Edit a file -- When the cursor is placed on a file as above, E lets you edit the file. Cursor positioning is the same. Additional control keys are Bksp, Delete Tab/Shift-Tab; Insert (toggles mode between Push Right and Overstrike); Enter (inserts the record delimiter previously selected with Ctrl-Enter; default is CR+LF). Ctrl-Y deletes line; Ctrl-D deletes to end of line. F1 or Alt-H provides a one-page help screen. Block operations are performed with Alt- {M (mark), Y (delete), V (move), C (copy), O (output to file), and P (print)}. Ctrl-F form-feeds the printer. Enter any ASCII code through Alt-Keypad numerical combinations, except NULL, which is entered by Alt-N. Esc exits Edit mode, and CF asks you if you want to save the edit. In most cases you will probably answer yes. Then it asks if you want to reuse the original, prior-to-edit file's date/time stamp on the revised file, and if you want to rename the original file as *.BKP. (When you do, CF deletes any previously saved file with the name *.BKP, even if it had a read-only attribute.) If it encounters problems with disk size or errors, it will give you further instructions. For example, if after saving the original file as *.BKP, it finds insufficient room on the source path to write the edited version of the file, it will instruct you to put a new disk in drive A, just so it can capture the edit for you. CMFiler -- Operation Reference OpRef-5 _________________________ TREE OPERATIONS: Cursor Movement -- Up/Down Arrow moves one screen line at a time. PgUp/PgDn moves to top or bottom of screen, then moves screen 19 lines, or to very top/bottom of tree. Home/End moves to very top/bottom of tree. Shift-Up/Down Arrow moves up/down one directory at same level (to next subdirectory up or down in parent directory), or, in "Goto file", "Goto directory" and "Find text" modes, to next directory with a match to the find string. P moves up to parent. Left/Right Arrow changes panels, making the other panel the source. Shift-Left/Right Arrow moves across to the path match in comapre mode. N -- New disk -- Allows changing drives or disks, as in main module. M -- Makes directory under path at cursor. 2 -- Toggle directory's hide attribute. Alt-L -- Prints a hard copy of the tree Listing shown on the source panel side of the screen in straight tree mode. Prints a listing of all the file matches while in Find file or Find text mode. D -- Delete structure -- deletes the entire structure highlighted in the cursor block in the source panel. This is a "soft" delete on hard disks, in which the deleted files are redated and collected in \CF_TRASH.CAN. Ctrl- D -- "hard" Delete structure. Uses the DOS file delete function regardless of disk type. Alt-D -- Delete just the file in the source directory. This is a "hard" delete. C -- Copy structure under target path -- Replicates the structure in the source panel's cursor block UNDER the directory selected in the target panel. Shift-C -- Move structure under target path -- If both panels selected to the same disk, moves the structure in the source panel's cursor block UNDER the directory selected in the target panel. If different disks selected, defaults to Copy. Alt-C -- Copy just the directory array under target directory, no files copied. I -- Copy structure Into target path -- Similar to copy, but does not replicate the highest level subdirectory in the source block, but rather puts its files directly INTO (vice UNDER) the target subdirectory, and replicates its substructure into the target path. CMFiler -- Operation Reference OpRef-6 Shift-I -- Move structure Into target path -- If both panels selected to same disk, moves the source structure INTO (vice UNDER) the target subdirectory, as with I. J -- Copy Just the files in source directory to target directory. Shift-J -- Move Just the files from the source subdirectory to target. S -- Show files in opposite panel. Arrow across to file list if desired, then up/down with normal cursor moves. In file list, Enter returns to main module, to directory and file selected. Arrow back to tree. Esc or S cancels "Show files". From file list, V or E to view or edit a file. G -- Goto file -- Type filename for search. Wildcards are supported. Positions to first match; directories with matches and matching files are highlighted. Shift-Up/Down Arrow seeks next directory up or down with match. Arrow across to file list as in "Show files", move up or down, arrow back to tree, or Enter to file in main module for file operation. Esc, G or Alt-G to cancel "Goto file" mode. From file list, Enter or E to view or edit a file. Alt-G -- Goto directory -- Type directory name for search. Navigation within tree and exit are same as G. Shift-F -- Find text -- Specify text to search for, and up to eight filenames with wildcards. Directories and files with matches are highlighted. Shift-O -- Toggle "file Overcopy" switch. With switch off (=N), files already extant in target with same date/time and size as in source are not overwritten. With switch on (=Y), they are. Ctrl-H -- Toggle the Hide switch and redisplays trees. With switch on (=Y), directories with hidden attribute are not displayed. With switch off (=N), hidden directories are displayed, and are denoted with a highlighted "*H" Ctrl-C -- Toggle the Compare switch. With switch on (=Y), target disk is searched for any path that matches that currently selected in source, and, if one is found, adjusts screen if needed so it is visible, and highlights it in high-intensity yellow. Enter -- From tree structure, returns to main module with currently selected path(s), and cursor positioned to top of listing. From file list in "Show files" or "Goto file" mode, views file. Shift- Enter from file list returns to main module with cursor on file. Esc -- Returns to main module with path(s) as set on entry. Alt-Q -- Quits CF altogether; default path as selected in source. CMFiler -- Operation Reference OpRef-7 _________________________ APPLICATION LAUNCHING (CHILD PROCESSES): S -- Shell to DOS -- Set up a DOS shell and do any DOS operations. Exit DOS with the "exit" command when finished. CF then looks for and tries to reestablish the current directories as they appeared in the panels at shell execution. Q -- Quick execute -- Immediately executes file under cursor, if extension is .COM, .EXE or .BAT. Paths are as selected, ie, default drive/current subdirectory is same as the executable file is in, and the current subdirectory for any other drive is as last set by you through a CF panel display. X -- prepare to eXecute with command line -- Readies file at cursor for execution. File remains ready awaiting execution, initiated by one of the followup key combinations Alt-X, Shift-X or Ctrl-X after paths are set and command line seeded as desired. Alt-X -- edit command line and initiate eXecution -- Opens a window for editing the command line containing any "seeds" placed by Alt-C and/or T or Alt-T. Execution of the readied application starts by pressing Enter. The previously used command line may be summoned by pressing the Up Arrow or PgUp. Shift-X -- initiate eXecution, no editing of command line. Same as Alt- X, except file executes command line as-seeded, with no editing. Tagged files in active panel are added to command line. Ctrl-X -- initiate eXecution, no editing of command line, and ONLY the file name under cursor is added as last entry in seeded command line. Tagged files in active panel are ignored. Alt-C -- seed Command line with file specification. Adds the full specification, including path, of the file under the cursor to the command line buffer, and shows status of command line being built. Command line may be added to using this feature before or after executable file is readied with X. T or Alt-T -- Tag the file names in order for addition to the command line. Tagged files are added to the seeded command line as the final step after Alt-X or Shift-X is pressed. Ctrl-Enter -- select delimiter for use by the "seeding" operations Alt-C and T or Alt-T between entries of command line. Choices are blank, comma, semicolon. CMFiler -- Operation Reference OpRef-8 Shift-F10 -- specify a user-defined executable file specification and optional default command line offering for up to 9 applications, assigned to F1-F9. Also specify ZIP/UNZIP command line default switches, and an access password. Ctrl-Enter to record selections in current copy of configuration file. Or Esc to cancel edit. Ctrl-Enter also records as default values for the next execution of CF.COM the current states of the Hide and Compare switches, and the current settings for file ordering mode, resident kernel size option, command line delimiter. F10 -- Display current entries F1-F9, Compress/Extract options, password. The commands F1-F9, Shift-F1-F9, and Ctrl-F1-F9 may all be issued from this display. F1-F9 -- ready a user-defined executable file spec -- Effect is same as locating the file with the cursor and hitting X. F-key default command line offering is added to command line, which may already have seeded entries. Shift-F1-F9 -- ready user-defined executable, add its default command line offering to the command line being built, add any Tagged files in current directory (active panel), and execute immediately. Ctrl-F1-F9 -- ready user-defined executable, add its default command line to the command line being built, add ONLY the file name under the cursor, and execute immediately. Tagged files in active panel are NOT added to the command line before execution. Z -- PKZIP (c) compression -- Be sure PKZIP.EXE is on one of the paths in your DOS path command, or specify the complete path spec to it using Shift-F10. To ZIP, select on one panel a target path for the compressed .ZIP file, and optionally Tag or Alt-Tag an existing .ZIP file. Then switch to the other panel and select a source path, optionally Tag or Alt-Tag files to compress in order of desired appearance on command line, press Z, edit command line if necessary, and press Enter. To avoid this extra Enter keystroke, hit Shift-Z instead. U -- PKUNZIP (c) extraction -- As above, be sure PKUNZIP.EXE is on a path set in your DOS path command, or specify the complete path spec to PKUNZIP.EXE with Shift-F10. To UNZIP, select on one panel a target path for the extracted files, switch panels, select the directory with the .ZIP file to be extracted, place the cursor on it, and press U. Edit command line, if necessary, and press Enter. Alternatively, for instant UNZIPping, use Shift-U. CMFiler -- Operation Reference OpRef-9 _________________________ DISPLAY ENHANCEMENT FEATURES: "+" and "-" -- Shift the file size display to expanded and contracted mode. Expanded mode shows explicit size, but uses the file time field. Contracted mode is in KB or MB. H -- Help -- Shows a three-page help screen with abbreviated explanation of the most-used operations. Ctrl-N -- edit Notes -- Displays the directory notepad in the opposite panel for viewing/entering/editing narrative comments about files. All the editing and cursor control key combinations work. Notes follow the files around when copied. CF updates the file on exit (Ctrl-Enter or Esc). Files may be viewed/editied from the Notes screen with Alt-V/Alt-E, tagged with Ctrl-T or Alt-T for subsequent mass action after exit from edit Notes. Shift-N -- view Notes -- Displays Notes in opposite panel, but leaves full access to all directory and file services in the source panel, including operations like Copy which operate to the target path. Ctrl-O -- select file Ordering mode -- Permits selection of one of seven modes of file ordering. Cursor shows current selection. Ctrl-H -- toggle Hide switch -- Changes the state of the hide-enable switch, shown at the top of the screen. With the switch on ("Y" for Yes), CF does not display files whose hide attribute is set. With the switch off ("N" for No), all files are shown. Ctrl-C -- toggle Compare switch -- Changes the state of the compare- enable switch. In compare mode ("Y"), any file in the target path whose name is the same as the file in the source path under the cursor will be shown and highlighted. Ctrl-M -- Mask -- Allows editing the Mask template for the panel, whose initial value is *.* Tab moves cursor to the extension field, Shift-Tab to the name field. Press Enter to enter the template modification and redisplay the panel. 5 -- Toggles date/time display on main screen. Ctrl-P -- color Pallette selection -- Allows user to change color scheme to any of four sets on color monitors.
