J A D U (Just Another Directory Utility) Version 1.3 October, 1989 J.C.

Ratjen All rights reserved. Hello! Thanks for trying JADU. I hope you find it as useful and easy to use as I have. You see, that's the whole concept behind JADU - simplicity and ease of use. I started JADU after becoming frustrated by other directory utilities, by their heavy use of function keys and mnemonics that were strained - to say the least. They also wouldn't let me use the utilities I'd become so dependent upon. Thus was JADU born. It was designed from the beginning to be a utility where the commands made sense (want to delete a file? Hit <Del>. Want to delete a directory? Hit <Del> for that too, not Alternate-F5 or some other nonsense). I also bore in mind that everyone has their favorite utilities and would probably want to use them without having to jump out to DOS to invoke them at the command line. JADU knows about archive utilities, editors, file viewers, file finders, and print utilities, and it doesn't limit you to any specific utility. You tell IT what utility YOU want to use. JADU also lets you specify actions you might want taken based on the file's extension AND its directory (a much more potent combination than just the extension alone). As most of you probably suspect by now, JADU is USER SUPPORTED SOFTWARE. For those of you new to the Wonderful World of BBS's, User Supported Software means that you are allowed to try JADU before purchasing it to see if it's what you're looking for. If you decide JADU isn't for you, so be it. If, on the other hand, you like JADU and continue to use it you are obliged to register. (Corporate and government users MUST register - call for special terms). Registration costs only $25 and brings with it telephone support, the latest version of JADU, notice of upgrades (plus a discount on those upgrades), a copy of the documentation and a clear conscience. Whether you register or not, I encourage you to spread JADU far and wide. Please pass it along in its original ZIP'ed form. You MAY NOT sell JADU! If JADU is distributed on diskette, you may charge up to eight dollars for materials, shipping, and handling, but no other fees may be collected. Many people have used JADU and found it to be just what they needed. However, it is solely *YOUR* responsibility to determine the fitness of this package to meet your needs. I will not be liable for damages of any kind arising from a failure of JADU to perform as expected. I would like to take this opportunity to thank all of the people that have contributed to the development of JADU. This is by no means a complete list, and I apologize to those I've forgotten. Ron Abernethy, Joe Apuzzo, Steven Dubin, Joe Krol, Ron Maffei, Judy Mella, Jack Pearson, Niki Shrode, Fred Villani, all of the folks at EMS, and, above all, my loving wife Camille. Page 1 Starting JADU Starting JADU is pretty easy. If you're in a hurry you can just rename the sample configuration file to JADU.CNF and type JADU (the sample file has been configured with some of the more popular shareware utilities - PKZIP, PKUNZIP, LIST, and QEDIT). The real power of JADU though is gained through the use of the JINSTALL program. Use it to let JADU know what utilities YOU will be using. JADU uses the configuration file not only to determine what utilities you want to use, but also to learn your choices for such things as screen colors, sorting order, and mouse speed (yes, JADU likes mice). Without the configuration file, JADU will still operate, although without the grace of the non-lobotomized version. The configuration file must be named JADU.CNF and, along with JADU.EXE, reside either within the current directory or in a directory pointed to by the PATH environmental variable. For example, if you had the following line in AUTOEXEC.BAT, PATH=C:\;C:\DOS;C:\UTILITY you could place the files in the root directory, C:\DOS or C:\UTILITY. (Personally, I'd choose C:\UTILITY. It's intuitive - JADU is a utility.) If JADU is unable to find the configuration file it operates with the following defaults: Normal color - white text on a black background Reverse color - black text on a white background Flicker prevention - off Scroll lock - remains as is Num lock - remains as is Sort key - name Mouse - not used See Appendices A & B for more information on the configuration file. There is an optional environmental variable that you may want to use. In order to speed startup, JADU can store the directory tree in a file called JADUDIRx.JDU, where x is the drive letter (C for drive C, etc.). Once this file is created JADU will read the tree information from it rather than scan the drive each time it starts. It will only do this if you define the variable JADUDIR to point to the directory JADU should use to store this file. For example, if you have the following line in AUTOEXEC.BAT: SET JADUDIR=D:\ JADU will save the tree information in the root directory on the D drive. If this variable was not set, JADU would scan the drive normally. Page 2 Use of this option can greatly decrease the amount of time it takes JADU to start up. Unfortunately, it can also lead to great confusion if you are not careful. Keep in mind that if you create a directory outside of JADU the file WILL NOT REFLECT THIS CHANGE. If you find that this has happened, or you do not see a directory you think should exist, use the pdate command to refresh the file. You can minimize the possibility of this happening by storing the file in a RAM disk or by modifying AUTOEXEC.BAT to delete the files on startup. Either of these will cause JADU to start the 'day' with an up to date file. (As of version 1.3 JADU checks all directories found while loading the files area against those in the directory tree and updates the tree if necessary, thus reducing the chances of 'phantom' directories). Page 3 The Display JADU's display is divided into three distinct sections - Status area (top), Directory tree (left), and File list (right). Allow me to discuss each in detail... Status area: The Status Area displays information about the current drive, directory and file (among other things). The top line displays the name of the current directory and the file selection mask. The current directory is pretty straight forward, but the idea of a selection mask may be new to some of you. The selection mask allows you to specify what files will appear in the file list. Normally the mask is set to '*.*' meaning "show all files", but it can be easily changed (with the <N>ew Path/Mask command) to the mask of your choice. For example, if you set the mask to '*.DOC' JADU will display only those files with an extension of '.DOC'. The remaining items in the status area are as follows: Total: the total capacity of the current drive, in bytes Free: the total number of unused bytes remaining on the current drive Used: the total number of bytes already used on the current drive Files: the total number of files in the current directory (not counting subdirectories or the volume label). Dir size: the total number of bytes used by the files in the current directory File size: the size of the current file, in bytes Directory tree: The Directory Tree is a visual representation of all of the directories on the current drive. Each sub-directory is shown below, and indented to the right of its parent. Page 4 As with all good things there are limits associated with the directory tree. First of all, only the first 150 directories will show on the tree. This should suffice in most cases (if the demand is there, I might be persuaded to increase the limit). Second, there is a limit of seven levels to any given directory. For example, \a\b\c\d\e\f\g is valid, as far as JADU is concerned, but \a\b\c\d\e\f\g\h is not (8 levels). The current directory is displayed in reverse. To change directories, simply use the movement keys (see below) to move the pointer to the desired directory and hit <RETURN> or point to the directory with the mouse and press both buttons. File list: All files in the current directory that match the file selection mask are displayed in the File list window, along with information about those files. They are displayed sorted according to the criteria you specify (either in the configuration file or with the <S>ort command). Up to 500 files can be listed in this area. The information displayed is as follows: File name: The file name is pretty self explanatory. Remember that only those files matching the file selection mask will be displayed. File size: The file size is shown ROUNDED TO THE NEAREST K (i.e. 1024 bytes). It is followed by an uppercase 'K' to remind you of this fact. The sole exception to this is files that would normally be rounded to 0K. They are shown as being 1K so as not to be confused with empty files. If you need to know the exact size, move the pointer to the file and check the 'File size' in the Status Area. If the file listed is actually a directory or the volume name, JADU will place <dir> or <vol> in place of the size. Attributes: Each file has several 'attributes' that can be manipulated by JADU. These are displayed after the file size. If the attribute is 'on' the corresponding letter will be displayed intense. The attributes are: Archive - displayed as a lowercase 'a'. This attribute is used by backup utilities to determine if a file has changed since the last time the file was backed up. If the attribute is off the file hasn't changed. If it's on, the file has changed and should be backed up. Hidden - displayed as a lowercase 'h'. If this attribute is on the file will not be seen by normal DOS commands (such as DIR). Read Only - displayed as a lowercase 'r'. If on, prevents the file from being deleted or changed by any DOS operation. Page 5 System - displayed as a lowercase 's'. This is a a holdover from CP/M. It will hide files like the Hidden attribute, but serves no real purpose under MSDOS. Date & time stamp: After the file attributes, JADU displays the date and time that the file was last modified. The time is shown in 24 hour format. Page 6 Movement/Action keys Left/Right arrows The left and right arrow keys allow you to alternate between the Directory Tree and File list areas. The active area will contain the pointers and have a double line as its top window border. Up/Down arrows The up and down arrow keys perform as you would expect - they move the pointer up or down by one file or directory. If you are using a mouse you can move up/down one file/directory by clicking the left button on the top/bottom window border. Home/End These keys will move the pointer to the top (or bottom) of the current 'page' of files or directories. A second press of the same key will move to the first (or last) file or directory in the list. If the pointer is already at the top (or bottom) of the page, you will only have to hit the key once to go to the first or last file. If you are using a mouse you can move to the first or last file/directory in the list by clicking both buttons in the top/bottom window border. PgUp/PgDn Move the pointer up and down by one 'page' (19 lines). If you are using a mouse you can page up/down by clicking the right button on the top/bottom window border. Keypad plus 'Tags' the file at the pointer position. You can perform a given action on many files if you tag them first. If you are using a mouse you can tag a file by pointing to it and clicking the left button. You can quickly tag all of the files in a subdirectory by tagging the '<current>' entry in the File list area or the highlighted directory in the Directory tree area. If you are one of those people hooked on function keys you can also use <F5> to tag all files. Keypad minus 'Untags' the file at the pointer position. If you are using a mouse you can untag a file by pointing to it and clicking the right button. Page 7 You can quickly untag all of the files in a subdirectory by untagging the '<current>' entry in the File list area or the highlighted directory in the Directory tree area. <F6> will also untag all files. Return The <RETURN> key has two functions. First it allows you to enter a directory by pointing to it and pressing <RETURN>. Second, if you point to a file other than a directory JADU will execute the command (if any) that you have defined for the file, based upon the file's extension and the current directory (see 'Execute' in the DOS commands section). If you are using a mouse the same functions can be accomplished by pointing to the file/directory and clicking both buttons. Space Toggles the tag on the current file (i.e. if it's tagged you'll untag it and vice versa). NOTE See the explanation of the <T>agged command to learn how to use the tag option. Scroll Lock Scroll Lock will cause JADU to automatically move the pointer down one line when you tag or untag a file, thus saving you a keystroke. (You can tell JADU to automatically activate Scroll Lock on program startup in the configuration file). <F3> <F3> will recall your last response to a given prompt. Response recall is command specific - that is it recalls the last answer you gave for that command. For example, if you press <F3> while at the Copy prompt you'll recall the last copy destination, even if you've answered a number of other prompts since that time. <F3> only works within the current session. Commands are not 'remembered' after you exit JADU. Page 8 Commands Archive Functions Pressing 'A' will cause JADU to display a submenu of Archive functions. These options are: Add: Option 'A' on the submenu. This will allow you to add a file (or several files, if the tag option is active) to an Archive. You will be prompted for the name of the archive. Extract: Option 'E' on the submenu. This causes all files in the target archive(s) to be extracted. You will be prompted for the destination directory (you can use the arrow keys to point to the destination on the directory tree). View: Option 'V' on the submenu. All of the files in the target archive(s) will be listed. A hint: If you find yourself using the 'V' or 'E' options a lot you can save time by utilizing a user defined function. For example, you could make JADU list all of the files in an archive by telling it to invoke PKZIP with the 'V' option whenever the <RETURN> key is pressed on a file with a '.ARC' extension. Please note that these functions will not operate unless you specify what Archive utilities to use in the configuration file. Copy The copy command is pretty straight forward. Press 'C' and JADU will prompt you for the destination. If you are copying more than one file you can only enter the path or a wildcard filename as the destination. If you are copying a single file you may enter a specific filename. As a quicker means of path entry, JADU allows you to use the arrow keys to point to the destination on the directory tree. If the file exists you will be prompted to confirm the copy before the old file is overwritten. If you are copying several files when this happens you will notice that besides the usual Y/N choices you also have 'G'. The 'G' stands for "Go To It". Press it and JADU will copy the rest of the files without prompting for confirmation if any of them already exist. Page 9 Create Directory You can easily create a directory by pressing <INS>. If you are in the File List area the directory created will be a subdirectory of the current directory. If you are in the Directory Tree area you will create a subdirectory of the directory at the pointer location. Date/Time functions Changing a File's Date: Pressing <F9> will prompt you for a new date for the target file(s). If you are using a mouse, just click either button on the date and you'll be prompted for the new date. Changing a File's Time: Press <F10> to change the file(s) time stamp. If you are using a mouse, just click either button on the time and you'll be prompted for the new time. Touching a File: Press <F4> to set the file(s) date and time stamps to the current date and time. Your system clock must be set correctly for this command to work. (I realize that these keys don't even come close to being mnemonics for the commands, but all of the good letters were already taken. I'll listen to any suggestions...). Delete Files and directories can be deleted by pressing 'D' or <DEL>. You'll be prompted for confirmation before the deletion will take place. One note - unlike files, directories cannot be tagged and deleted. This was done on purpose as a safety measure (it's not a bug, it's a feature). Unlike DOS, JADU allows you to delete the current directory. It simply moves you to the parent before the deletion (why can't DOS do that?). DOS Commands There are two methods you may use to execute DOS commands in JADU: Internal Command: Pressing '>' will cause JADU to open a window and prompt you to enter a DOS command. The screen will then clear and the command will be executed as if you had typed it at the DOS prompt. When the command is completed you will be prompted to hit a key before returning to JADU. Page 10 This command is easier to remember than it may at first appear if you keep in mind that DOS terminates its normal prompt with the angle bracket. Jump to DOS: If you have more than one DOS command that you want to execute you might want to temporarily <J>ump to DOS. This will create a DOS shell in which you can enter commands as if you were at the normal DOS prompt. When you are through simply type 'EXIT' to return to JADU. NOTE: It's easy to forget that you are in JADU's shell rather that at the regular DOS prompt. If you are unsure which is the case just type 'EXIT' (there's no effect if you are at the regular prompt). Alternately you can try to run JADU (it knows when it's running already and will tell you). Edit Press 'E' to edit the target file(s). Please note that Edit will not operate unless you specify what editor JADU should use in the configuration file. 'Execute' Pressing <RETURN> while on a file will 'execute' a user-defined action based upon the file's extension and the current directory (point to the file and click both buttons on the mouse to accomplish the same thing). These actions are specified in the configuration file and can be entered or changed with the install utility or an editor. See Appendices A and B for more information on the configuration file. Exiting the Program You can exit JADU by one of two methods. Pressing either 'X' or <ESC> will exit the program and return you to the directory in which JADU was started. Pressing 'Q' will 'quit' the program and remain in the current directory. File Attributes, changing The file attributes can be toggled using the 1,2,3, & 4 keys. The numbers directly correspond to the 'ahrs' in the File list display. For example, pressing '1' will toggle the Archive attribute, pressing '2' will toggle Hidden, etc. (the keys may not be mnemonics, but they should be easy to remember.) Page 11 Find File If you are looking for a particular file, but don't know where it is located you can use JADU's file find capabilities. Press 'F' and you will be prompted for the name of the file you want to find. If you specified an external utility to use for this purpose JADU will invoke it and pause before returning to the main program. If you did not, JADU will use an internal routine to search all directories on the current drive for the file. The internal file finder will notify you if it finds what you are looking for, and give you the option of going to the file. If you answer 'Y'es JADU will change directories and move the pointer to the file. Specifying 'N'o will continue the search. 'Q'uit ends the search. Help Pressing 'H', '?', or <F1> within JADU will display a help screen containing a summary of the commands. If you are using a mouse you can obtain help on the mouse commands by hitting the space bar while the main help screen is displayed. Additional information pertaining to your version of JADU can be obtained by pressing 'I' (outside of Help). List/View Pressing either 'L' or 'V' will invoke the File View program you specified in the configuration file to look at the current file (or files if the tag option is active). If you didn't indicate which program to use, JADU will complain and the command won't work. Move You can move a file from one directory or drive to another by pressing 'M'. Move has the same restrictions regarding destination names as the Copy command. Also like Copy, you can use the arrow keys to indicate the destination path on the directory tree. Normally files are moved by simply changing their name. If you are moving the file(s) to a different drive, or you are using DOS 2.x, move works a little differently. In these cases a quick rename will not work. JADU knows this and will compensate by first copying the file to the destination and then deleting the original. The result is the same, just a bit slower. Page 12 New Path/Mask You can specify a new path or file selection mask by pressing 'N'. You will be prompted for the new path/mask. For example, if you want to see all of the '.COM' files in your UTILITY directory you could enter 'C:\UTILITY\*.COM'. You can also use this command to change drives. One quick warning - it's easy to forget that you've changed the mask. If you don't see as many files as you believe there should be, check the file selection mask. It's more than likely the cause. Print Pressing 'P' will display the Print options submenu. Items on the submenu are as follows: File(s): Option 'F' on the submenu. This will invoke the print utility of your choice to print the current file (or files if the tag option is active). Please note that if you chose to use DOS Print there is, unfortunately, a price to pay. DOS Print allows a maximum of ten files to be in queue at any given time. If you have tagged more than the limit only the first ten will be printed. Directory: Option 'D' on the submenu. This will cause JADU to print a list of the files in the current directory in the same format as the File list area. File attributes are printed in uppercase if they are on, lowercase if they are off. Tree: Option 'T' on the submenu. Pressing this will make JADU print the directory tree. Your printer must be capable of printing line graphics. Rename Pressing 'R' will allow you to rename a file or directory (you must have DOS 3.x to rename a directory). You can rename multiple files at one time by first tagging them and then using a filename containing wildcards for the new name. Refresh screen Pressing <F7> will refresh the screen. This is useful if you get the DOS 'Insert disk for drive x' message. (If anyone knows how to trap this message please drop me a line.) Page 13 Sort Pressing 'S' will display the Sort option submenu. Items on the submenu are: Date: Option 'D' on the submenu. This will cause the File list to be sorted according to the file's date/time stamp. The most recent files will be displayed first. Extension: Option 'E' on the submenu. Files will be sorted in alphabetical order based upon the file's extension. In the case of duplicate extensions the file name will be used as a tie-breaker. Name: Option 'N' on the submenu. Files will be sorted in alphabetical order based on the full file name. Size: Option 'S' on the submenu. Files will be sorted in size order, from largest to smallest. Tagged: Option 'T' on the submenu. This behaves the same as the <N>ame option with the exception that tagged files are moved to the top of the File list. Tag active Pressing 'T' or <F2> activates the tag option. This informs JADU that you wish to perform the next command on all of the tagged files. If the next command does not accept tagged files the option is turned off. An alternative to pressing 'T' before a command is to hold down the <ALT> key while pressing the command. For example, pressing <ALT>- C is functionally equivalent to pressing 'T', then pressing 'C'. Update Pressing 'U' updates JADU's directory and file information. It accomplishes this by performing a full reload based on the current path. This is most useful when JADU is displaying floppy-based information and you wish to change diskettes. After placing the new floppy in the drive, hit 'U' and the old information will be replaced. Page 14 This command can also be used to update the drive's directory save file (if you defined JADUDIR - see 'Starting JADU'). The pdate command does not read tree information from the save file, rather it scans the disk and recreates the file. In this way you can correct a save file that has gone 'out of synch' with reality (usually caused by creating directories outside of JADU). WildCard Tag Many files can be tagged at one time by pressing 'W'. JADU will then prompt you for a wildcard specification and tag all of those files in the current directory that match it. For example, specifying '*.DOC' will tag all files with an extension of '.DOC'. While programming JADU I noticed that most people use the wildcard tag feature to tag files based upon the file extension. As a result I placed a shortcut in JADU that allows you to hit the asterisk to invoke wildcard tag. Unlike hitting 'W' this will prime the wildcard specification with a leading '*'. For example, if you want to tag all files ending with '.BAK' you don't have to type 'W' then enter '*.BAK' at the prompt. You can simply type '*.BAK'. This is a lot easier to use than it is to describe. Try it. I think you'll like it. Page 15 APPENDIX A Configuration File Specifications The configuration file is simply a list of parameters that JADU needs to know before it can operate. It must be named JADU.CNF and reside in the current directory or in a directory pointed to by the PATH environmental variable. Most people will not need the following specifications - the install program should be enough. For those of you who want a bit more control, this kludge is for you... The parameter file is made of three distinct sections, each being little more than a comma separated list of data. Section one deals with initialization of system variables. It consists of one line. Section two is seven lines long and describes your preferred utilities (archiver, LISTer, etc.). Section three can be up to 20 lines long. It describes optional actions to be taken based on the directory and file extension of the current file. SECTION 1: The following parameters must be on the first line of the file, separated by commas, and without embedded spaces. param 1 - 'normal' attribute This is a hexidecimal number describing the color used to display all non-highlighted information on the screen. It conforms to the normal IBM convention where the lower 4 bits represent the foreground color and the upper 4 bits represent the background Page 16 color. Well, almost. JADU intensifies the normal color in certain situations to make the information stand out (for example, the file attributes are intensified when they are set). In order to do this the 4th bit of the foreground color is set. This leaves you with 3 bits for the foreground. (Since setting the 4th bit of the background attribute causes the text to blink on color screens you may not want to use it either). If you're now totally confused, I'll simplify it for you. Think of the color number as 2 digits where the first digit represents the background color and the second digit represents the foreground color. Valid colors are in the range 0-7 as follows: 0. black 1. blue 2. green 3. cyan 4. red 5. magenta 6. brown 7. white For example, if you want JADU to display information in white on a blue background the color number would be 17. 'Nuff said. param 2 - 'reverse' attribute This is also a hexidecimal color number. The 'reverse' color is used when files are tagged, as well as for some system messages. The same rules apply as for the normal attribute. Generally you just reverse the background and foreground bits (i.e. use the 'normal' foreground as the 'reverse' background and vice versa - the white on blue example above would use 71 (blue on white) as the 'reverse' color). param 3 - Flicker Prevention flag Certain older color video cards have difficulty handling information written to the screen via direct memory access. The problem presents as a flicker or 'snow' whenever something is written to the screen. JADU can prevent this flicker, though at the expense of some of DMA's speed. Generally, you should use '1' only if you are having this sort of problem. 0 = No flicker prevention 1 = Flicker prevention Page 17 param 4 - Default Sort Key This is a letter describing the way the files are sorted when JADU is first started. The valid codes are as follows: D - sort on file date E - sort on file extension N - sort on file name S - sort on file size T - sort on file name, tagged files first param 5 - Scroll Lock flag The Scroll lock causes the pointer to move to the next file in the list when you tag or untag the current file. 0 = Scroll lock off when JADU is started 1 = Scroll lock on when JADU is started 2 = Leave Scroll Lock as found when JADU is started JADU will return Scroll Lock to its original state when you exit the program and when you run other programs from within JADU. param 6 - Num Lock flag Num Lock doesn't accomplish anything in particular within JADU. I added this toggle for people like myself who prefer to use the keypad rather than the separate arrows keys and such on the new style keyboards. JADU will return Num Lock to its original state when you exit the program and when you run other programs from within JADU. 0 = Num Lock off when JADU is started 1 = Num Lock on when JADU is started 2 = Leave Num Lock as found when JADU is started The three remaining parameters are only used if you have a Microsoft compatible mouse installed in your computer. param 7 - Use Mouse flag 0 = No mouse or ignore the mouse (and the next 2 parameters) 1 = Use the mouse param 8 - Mouse Horizontal Speed param 9 - Mouse Vertical Speed These 2 parameters are decimal numbers representing the ratio of mouse movement on your table to cursor movement on the screen. The smaller the number is the less you'll have to move the mouse to Page 18 cover a given distance on the screen. Your best bet would be to use a horizontal value of 8, and a vertical value of 16 to start. Then modify each until you're satisfied (the install program is easier). SECTION 2: This section consists of seven separate lines, each comma delimited. Each line describes a particular utility and associated actions. The lines refer to (IN ORDER): line 1 - Archiver line 2 - deArchiver line 3 - Archive viewer/lister line 4 - Editor line 5 - File viewer line 6 - File finder - optional, if the parameters are left blank JADU will use its internal file finder. line 7 - Print utility Each line consists of five parameters: param 1 - Reread Flag This flag tells JADU what action to take after executing the specified utility. The values are as follows: 0 = Do not reread. Simply return to JADU. This is used when the utility does not change any information in the current directory (a good example is a file viewing utility). 1 = Complete reread. The entire directory is reloaded. 2 = Rescan target. This rescans only the files affected by the command. param 2 - Wait Flag This controls whether JADU will pause after running the utility, or simply return to the program. 0 = Don't wait, just return. 1 = Display "Hit any key..." message and wait for a key to be hit before returning to JADU. param 3 - Multi-file Flag Many utilities allow more than one target file to be passed on a single line. Most archive utilities, for example, permit you to archive several files at a time by listing them on the command line. If this flag is set, and you are doing the specified action Page 19 on a group of tagged files, JADU will put as many files on the command line as will fit within the DOS imposed 128 byte limit. If all of the files do not fit, JADU will re-issue the command with the next set of files and continue to do so until all of the files have been passed. An exception to this is when JADU notices that all of the available files are tagged. In this case JADU will use '*.*' in place of the list of files. 0 = Multiple files not allowed. 1 = Use Multi-File option where applicable. param 4 - BLANK (as in not used) It's here only to retain compatibility with SECTION 3 (I told you it was a kludge). Just put another comma and continue on to param 5. param 5 - Command Line This is the command as you would enter it at the normal DOS prompt, without the target file name. JADU will append the target file to the end of this command to invoke your utility. There is one special case. The archive utility will have the name of the archive appended first, then the file(s) to be archived. SECTION 3: This Section specifies up to 20 user defined actions. Each is dependent on the current file's extension and, optionally, the current directory. The format of each line is similar to those in Section 2 - five fields, separated by commas. param 1 - Reread Flag This flag tells JADU what action to take after executing the specified command. The values are as follows: 0 = Do not reread. Simply return to JADU. This is used when the command does not change any information in the current directory. 1 = Complete reread. The entire directory is reloaded and tagged files are reset to the untagged state. 2 = Rescan target. This rescans only the file affected by the command allowing you to return to JADU much more rapidly than if all of the files were reloaded. An additional benefit is that all tagged files remain tagged. There is one drawback though. If you create or modify another file from within Page 20 whatever program you are running JADU will not know about it. If you created the file, it won't show on the file listing. If you modified it, the current information will be wrong. (The situation can easily be corrected by hitting <RETURN> on the '<current>' entry in the file list or the directory name in the directory list, thus reloading the entire directory.) param 2 - Wait Flag This controls whether JADU will pause after executing the command, or simply return to the program. 0 = Don't wait, just return. 1 = Display "Hit any key..." message and wait for a key to be hit before returning to JADU. param 3 - Target Extension This is the file extension (without the dot) that must be matched in order for the given command to be used. param 4 - Target Directory This is the full path (drive + directory) which must be matched in order for the command to be executed. It should not terminate in a backslash unless you are specifying the root directory. This is an optional parameter. If you don't want the specified action to be limited to any one directory simply leave this parameter out, put in the next comma, and proceed to param 5. Please note that several of the lines in this Section can target on the same extension if given different target directories. If your configuration file contains several lines with the same Target Directory as well as one without, make sure that the one without the directory is placed last. param 5 - Command This is very similar to param 5 in Section 2 with one exception - you can specify the target file format through the use of a macro. This allows a little more control over the final product. The macro consists of a pair of curly braces containing any combination of five codes. The codes are as follows: Page 21 D - Drive letter + colon E - File extension (without the dot) F - Full file name (name.ext, no path) N - File name only, no extension P - Full path, no drive letter, always terminated with a backslash Anything else is treated as a literal character and is inserted as is. The following are some examples, assuming that the full file specification is C:\UTILITY\TEST.DOC {D} = C: {P} = \UTILITY\ {F} = TEST.DOC {DPF} = C:\UTILITY\TEST.DOC {NE} = TESTDOC {N.E} = TEST.DOC (note that the dot was specified within the braces and was inserted in the final product as a literal character) Page 22 APPENDIX B Sample Configuration File Page 23 07,70,0,N,1,0,0 section one 2,0,1,,C:\UTILITY\PKZIP.EXE -A section two 2,0,0,,C:\UTILITY\PKUNZIP.EXE | 0,1,0,,C:\UTILITY\PKZIP.EXE -V | 2,0,1,,C:\BRIEF\B.EXE | 0,0,1,,C:\UTILITY\LIST.COM | ,,,, | 0,0,0,,C:\DOS\PRINT.COM V 1,0,ARC,,C:\UTILITY\PKUNZIP.EXE {F} section three 1,1,BAT,,{F} | 1,1,COM,,{F} | 1,1,EXE,,{F} | 2,0,ASM,,C:\BRIEF\B.EXE {F} | 2,0,C,,C:\BRIEF\B.EXE {F} | 2,0,DOC,C:\WORD,C:\WORD\WORD.COM {F} | 0,0,DOC,,C:\UTILITY\LIST.COM {F} V Page 24 WHAT IT ALL MEANS: SECTION ONE: 07,70,0,N,1,0,0 | | | | | | | | | | | | | +----------> Mouse not installed or not wanted | | | | | +------------> Force Num Lock off when JADU started | | | | +--------------> Force Scroll Lock on when started | | | +----------------> Initially sort by NAME | | +------------------> Don't use flicker prevention | +---------------------> Reverse color is black on white +------------------------> Normal color is white on black SECTION TWO: 2,0,1,,C:\UTILITY\PKZIP.EXE -A 2,0,0,,C:\UTILITY\PKUNZIP.EXE 0,1,0,,C:\UTILITY\PKZIP.EXE -V 2,0,1,,C:\BRIEF\B.EXE 0,0,1,,C:\UTILITY\LIST.COM ,,,, 0,0,0,,C:\DOS\PRINT.COM The following utilities will be used: Archiver (line 1) PKZIP, found in the UTILITY directory on drive C: will be used to handle all requests to archive information (notice the '-A' option being used on the command line). JADU will only reread information pertaining to the archive file that is created/updated (param 1) and will return directly to JADU when the file(s) are archived (param 2). The '1' in param 3 indicates that PKZIP will accept multiple files on a command line. deArchiver - (line 2) PKUNZIP, also found in the UTILITY directory on drive C: will be used. All other parameters are the same as for the archive utility, with the exception of param 3, the Multi-File flag which indicates that PKUNZIP cannot handle multiple files. As such, JADU will use multiple calls to PKUNZIP to decompress more than one file. Archive view - (line 3) PKZIP will be used with the '-V' option to list the files contained in an archive. Since nothing should have changed JADU will not reread information pertaining to the target file (param1). Param 2 indicates that JADU should pause before returning to the main program. Page 25 Editor (line 4) B.EXE, found in the BRIEF directory on the C: drive will be used whenever you hit 'E' to edit a file. All other parameters are the same as for the archive utility. File view (line 5) LIST.COM, found in the UTILITY directory on the C: drive will be used to view/list files. JADU will NOT reread information pertaining to the target file and will return directly to JADU when you exit from LIST. The '1' in param 3 indicates that LIST accepts multiple files on the command line. File find (line 6) The parameters have been left blank, so JADU will use its internal file finder. Print (line 7) PRINT.COM, found in the DOS directory on the C: drive will be used to print files. SECTION THREE: 1,0,ZIP,,C:\UTILITY\PKUNZIP.EXE {F} This line specifies that JADU will run PKUNZIP whenever you hit <RETURN> while on a file ending with '.ZIP'. The fourth parameter has been left blank, so this will occur no matter what directory you are in at the time. Param 1 indicates that JADU should reload the entire directory after reArchiving the file (think of all those new files). Param 2 tells JADU not to bother waiting when its done, just return to the main program. For example, if you hit <RETURN> while on the file 'WHATZA.ZIP' JADU will pass the following command to DOS: C:\UTILITY\PKUNZIP.EXE WHATZA.ZIP Note that the full file name was used as per the {F} macro. JADU would then return to the main program and reload all of the files in the directory. 1,1,BAT,,{F} 1,1,COM,,{F} 1,1,EXE,,{F} These lines allow you to execute batch, '.COM', and '.EXE' files by simply hitting <RETURN> while on the file name. Since there is nothing specified in the command parameter besides the file name macro, that's all that will be passed to DOS. This will occur in all directories. JADU will then prompt 'Hit Any Key...' before returning to the main program. Once it has returned, the directory Page 26 will be reloaded. (The one exception to all of this, by the way, is JADU itself. You cannot execute JADU by hitting <RETURN> on JADU.EXE because JADU can tell when it's already running and will not allow you to run a second copy - after all, that would be redundant.) 2,0,ASM,,C:\BRIEF\B.EXE {F} 2,0,C,,C:\BRIEF\B.EXE {F} These lines indicate that JADU should run BRIEF (an excellent editor, by the way), whenever you hit <RETURN> on C or assembly source files. Once you exit the editor, JADU will not prompt you to hit a key before returning to the main program. JADU will then reread only the information pertaining to the target file. For example, if you hit <RETURN> on TEST.C JADU will invoke the editor as follows: C:\BRIEF\B.EXE TEST.C Once you are through editing the file, JADU will return to the main program and reread only the information about TEST.C. 2,0,DOC,C:\WORD,C:\WORD\WORD.COM {F} 0,0,DOC,,C:\UTILITY\LIST.COM {F} These two lines are an example of the conditional execution of commands based on the current directory. If JADU is asked to execute a file ending in '.DOC' it will first check to see if you are currently in C:\WORD. If you are, JADU will invoke WORD. If you are not, JADU will invoke LIST. Please note that the user action WITHOUT the directory parameter was specified last. This is because JADU checks the user actions sequentially. If you had specified the LIST action first, it would always be matched before JADU reached the WORD user action. JADU will reread the target file's information if WORD is invoked, otherwise it will not do a reread. Page 27 APPENDIX C List of Utilities Page 28 The following are just some of the utilities that will work with JADU. Inclusion in the list is not meant to be an endorsement for a particular utility. Conversely, if your favorite program isn't here it simply means that I am not aware of it or it slipped my mind while I was writing these docs. In either case if you send me a note I'll be happy to include it in the next revision of the manual. Special thanks to Dan Doman for allowing me to raid his bulletin board while I compiled this list. You'll notice Dan's name below as the author of some of the utilities. He is also the author of an excellent bulletin board system called dBBS, as well as several other utilities. His board can be reached at (212)427-1805. Categories: 1. File compression/Archiver 2. File decompression/deArchiver 3. Archive viewer/lister 4. Editor 5. File viewer/lister 6. File finder 7. Print utility 8. File manager - Yeah, JADU's competitors. If for some reason you don't like JADU, perhaps one of these will be more your style.

Rahul Dhesi Page 30 APPENDIX D Revision History Page 31 ======================================================================= Version 1.3 ======================================================================= -> Fixed some annoying 'features' in the input routine. First, JADU will no longer remember that you went into insert mode (ie. you will always begin in overstrike mode). Second, the <End> key now places the cursor at the end of what you have typed - not at the end of the input field. Last, if you begin to type over an existing item (such as the default directory in copy or move operations) the remainder of the line will be blanked out (no more pressing the space bar). -> Made the utilities section of the configuration file case insensitive, thereby allowing lowercase command switches. -> Fixed a bug in the utilities section of the configuration file that disallowed the use of batch files and didn't allow the use of command switches with certain utilities. -> Usage of the <Home> and <End> keys in the entry of a destination directory (copy and move commands) has been changed. Previously these keys moved the pointer on the directory tree. They now act as editing keys, moving the cursor to the beginning and end of the information being entered. -> The number of files displayed in the status area no longer counts directories or the volume label. Only 'true' files are included. In the same vein, the tag command no longer tags directories or the volume label. -> JADU will now pass '*.*' to your utilities if you have marked them as accepting multiple files and all of the files in the current directory are tagged. For example, if there are 10 files in the current directory, you only have 9 tagged, and you wish to edit them with an editor that accepts multiple files on the command line, JADU will (probably) make 2 invocations of the editor to achieve this end. If all 10 were tagged then only one pass would be needed (EDIT *.*). This is especially handy when you want to archive an entire directory of files. -> Fixed the pause option in the utility section of the configuration file. (Please note that prior to this version the Archive View command paused no matter how this parameter was set. If you still wish JADU to do this you must make sure that the parameter is set correctly.) -> Added <ALT-X> and <ALT-Q> commands which exit and quit without waiting for confirmation. Page 32 -> The directory deletion routine was rewritten to make it a bit smarter. This should reduce the odds of getting a "deletion not completed" message if the directory tree gets out of sync with reality. -> Added automatic discovery of new directories. Prior to this version if you created a directory outside of JADU (with the MD command, for example) it would not show on the directory tree, thus creating confusion. Now JADU checks each directory found while loading the files area to see if it exists in the directory tree. If it does not exist the tree is updated. -> Added the ability to specify a destination directory for files extracted from archives. This eliminates the need to first copy an archive into the destination directory before decompressing the files. This feature uses the same interface as the copy and move commands (point to the directory and hit <Return>). -> Added the <ALT-I> command to display the version timestamp. ======================================================================= Version 1.2 ======================================================================= -> Fixed bug where JADU tied up all the room remaining on a disk if a copy or move bombed due to insufficient disk space (you then had to do a 'chkdsk /f' to free the space) -> Changed directory tree double lines to single lines to provide a bit more separation from the window border. -> Fixed bug that made JADU hang on systems running DOS version less than 3.0 which did not have a mouse. -> Tweaked and twiddled some internal code. ======================================================================= Version 1.1 ======================================================================= -> Fixed bug in which the deletion of the current directory was attempted. You will now move to the parent of the you are trying to delete and the deletion will be allowed. -> Tagged files now remain tagged if you rename them -> Version 1.0's docs incorrectly stated that the maximum number of directories allowed was 150 (actually it was 100). The limit is now 150. -> JADU no longer converts DOS commands to uppercase, thus allowing case sensitive switches to be used. Page 33 -> Fixed a bug which disallowed the use of an external file finder. Now allowed (as it should have been all along). -> Fixed bug where JADU went through the motions of allowing you to rename the root directory -> Added the new command pdate to reload all directory information. This allows the easy changing of disks in floppy drives, if nothing else (IE. you no longer have to use the <N>ew path command when changing floppies, just hit 'U') -> Fixed bug where copied files received the current date, not the date of the original file. -> Removed check for '.ARC' file extension in ARC commands. You can now use any compression/extraction/library utility you want. -> The keyboard buffer is no longer cleared on startup, so typeahead is now possible while you're waiting for the directory/file scan to complete. -> The BIOS read/write option no longer exists. It was of doubtful use to begin with, was extremely slow and annoying to use, and (most of all) I needed the room. Needless to say, the F8 command has gone the way of the dinosaur. So has the BIOS/DMA field in the configuration file (see CHANGES.CNF). -> Flicker prevention can only be specified in the configuration file now (i.e. F7 will no longer toggle the option). -> JADU now allows the use of any print utility. An additional line has been added to the configuration file for this purpose. If you wish to continue using DOS Print you must specify it on this line (see CHANGES.CNF) -> Fixed bug in which the Print Tree and Print Directory commands occasionally did not print the last few lines until the next print command. -> The file name display has been changed to look like the DOS DIR display (i.e. the extensions line up) -> The single dot and double dot directory entries have been replaced with '<current>' and '<parent>'. -> The '0K' file size has confused many people. To avoid confusion only those files that actually contain 0 bytes are now marked as '0K'. Files where the size rounds to zero are marked '1K'. All others are marked with their true rounded size. Page 34 -> Added feature in which JADU will retain a data file containing the directory tree information. This file will be kept only if the environmental variable JADUDIR has been defined. (You can use the new pdate command to reload all directory information if the data file gets out of sync). USERS OF VERSION 1.0 PLEASE NOTE THIS CHANGE IN THE USE OF 'JADUDIR'. IF YOU WERE USING 'JADUDIR' TO TELL JADU WHERE TO FIND THE CONFIGURATION FILE AND DO NOT WANT TO SAVE THE TREE INFORMATION YOU MUST REMOVE THE 'SET JADUDIR' LINE FROM YOUR AUTOEXEC FILE AND MOVE THE CONFIGURATION FILE TO A DIRECTORY POINTED TO BY THE 'PATH' VARIABLE. SEE 'Starting JADU' FOR DETAILS. -> nfo command shortened to make a little more room. -> Added Refresh screen command (F7). I know it's not a mnemonic but the only other command I could think of was <K>lean screen. <Yuk!> Any suggestions are appreciated. -> Added <Q>uit option to the <F>ind command -> You can now specify that Scroll Lock and Num Lock be left alone when JADU is started. Simply use a '2' instead of '0' (off) or '1' (on) in the configuration file. ======================================================================= Version 1.0 - Original release ======================================================================= Page 35 <F1> 12 Find File command 12 <F2> 14 Flicker Prevention flag 17 <F3> 8 Help 12 <F4> 10 Home/End 7 <F5> 7 JADUDIR 2 <F6> 8 JINSTALL 2 <F7> 13 Jump to DOS 11 <F9> 10 Keyboard 14 <F10> 10 home/end 7 Archive Functions 9 keypad minus 7 Attributes 5 keypad plus 7 Bug fixes 33 left/right arrows 7 Changing directories 5, 8 PgUp/PgDn 7 Colors 17 return 8 Command scroll lock 8 refresh screen 13 space 8 Commands up/down arrows 7 'execute' 11 Keypad minus 7 Archive functions 9 Keypad plus 7 changing file attributes 11 Left/Right arrows 7 copy 9 List/View command 12 create directory 10 Modifications 33 date/time functions 10 Mouse flag 18 delete 10 Mouse Horizontal Speed 18 DOS commands 10 Mouse Vertical Speed 18 edit 11 Move command 12 exit 11 Movement/Action keys 7 find file 12 Multi-file Flag 19 help 12 New Path/Mask command 13 list/view 12 Num Lock 18 move 12 PgUp/PgDn 7 new path/mask 13 Print command 13 print 13 Refresh screen 13 rename 13 Registration 1 sort 14 Rename command 13 tag activation 14 Reread Flag 19, 21 update 14 Return 8 wildcard tag 15 Revision History 32 Concept behind JADU 1 Sample Configuration File 24 Configuration file 2, 16 Scroll Lock 8, 18 Copy command 9 Sort command 14 Create Directory 10 Space 8 Date & time stamp 6 Starting JADU 2 Date/Time functions 10 Status area 4 Default Sort Key 17 Tag option 14 Delete command 10 Target Directory 22 Directory tree 4 Target Extension 22 DOS Commands 10 Touching a File 10 Edit command 11 Up/Down arrows 7 'Execute' command 8, 11 Update command 14 Exiting JADU 11 User defined actions 21 File Attributes, changing 11 Utilities 30 File list 5 Wait Flag 19, 22 File managers 30 WildCard Tag command 15 File name 5 File selection mask 13 File size 5
