But you may do so to show your support. You may register in the following way: 1) Send me a letter telling me that you are using the program and/or by filling out the enclosed (read the READ.ME file) questionnaire and send it back to me (I prefer both); 2) Send me $5 for donation or as much (or less) as you want; 3) Send me $10, and I will send you either the most recent version, or next released version (your choice), along with your registration number labeled on the disk and embedded into this manual and program. ($5 will be donation, and the other $5 for materials.) Please tell me what disk type you need - 5.25" floppy or 3.5" Micro; 4) Send me as much as you want (over $10) and I'll send you everything you'll get in choice 3! :-) I might even send you new versions when they are released! If you have registered by sending me at least $5, you may receive upgrades for $5 (or download them and get it for free!) by sending me a letter telling me what version you are currently using (so I won't send you the latest one if you already have it.), disk type, and address if you moved. You will get everything you will get in choice 3 above. The $5 will be used for materials and shipping costs. If you send me a letter or the questionnaire, you may receive an upgrade by sending me $7. It's not as good as registering because you'll have to send me $7 everytime, so either send me $10 or, like I said before, download the program somewhere. The diskette, if I sent you one, will be warranted against defects in materials and workmenship for a period of 60 days fro mthe date of shipment by us. Any returned diskettes found bad will be replaced at no charge. If you do not have a printer and wish to have a hard copy of this manual, just sent $15 to me and I'll send you a copy. It will be formatted with a word processor to look as professional as possible. Also I will capture some screens and place it in there for examples. exDEL 1.01 1 Table of Contents ================= Table of Contents ............................................... 1 Introduction .................................................... 2 System Requirements ............................................. 3 Getting Started ................................................. 4 Installing the program on hard disk ........................ 4 Running exDEL .............................................. 4 Syntax ..................................................... 5 Command-line Options ....................................... 5 Rules ...................................................... 6 Examples ................................................... 6 Error Messages ............................................. 7 Comments from the author ........................................ 8 exDEL 1.01 2 Introduction ============ exDEL is a utility in which suppose to replace the DOS internal command DEL. Originally I planned on writing a utility to delete all the files I did not specify on the command-line but went off track and wrote this one in which is in some way an improvement to the DEL command. Of course, I will implement my original idea into exDEL as soon as possible. Current version of exDEL only included one major and two minor features compared to the DEL command. First, the minor features - 1) It could tells you how many files has been deleted; 2) It could display what files has been deleted. Of course, you could turn off both of these commands and use exDEL like DEL where it doesn't display anything. Now, for the major feature - 1) It could accept more than one file specification to delete! (DEL only accepts one) Basically, it could be as much as you could fit on a DOS command line, which is about 128 characters. exDEL 1.01 3 System Requirements =================== exDEL requires an IBM or compatible computer running DOS 3.0 or higher. However, I have never tried to use it with any DOS versions under 3.3, but they should work (including 2.0). Try it and tell me. Since this is only a command-line utility, it will work with any screen type, although a display with 80 columns is recommented. This version do not use color but future version may, if you have a color monitor. A disk drive is essential. exDEL has been tested one the following: - 80286 compatible. (AT) - 80386 compatible. (AT) - Microsoft DOS 3.3. - Digital Research DOS 5.0. - Microsoft Windows 3.0. - Novell ELS Netware 286 Level I Kit. - 1.2 megabyte disk drive. - 1.44 megabyte disk drive. - 40 and 80 megabyte hard disk. - VGA card and monitor. - Monochrome card and monitor. exDEL 1.01 4 Getting Started =============== Installing the program on hard disk ----------------------------------- To install the program, simply go to you hard disk and make a directory for exDEL (MD exDEL). Then copy everything in the exDEL archive or disk into that directory. I suggest change the path to include exDEL. A better way is to setup a directory (if you don't already have one) where you place all your commonly used utilities and copy exDEL into it. The directory should be included in the path. Running exDEL ------------- Unlike other applications, exDEL is not written to be ran without any command-line options. If you were to do so, the following screen will be displayed: exDEL 1.01 - S/N 51102740101 - Released 6-6-1991. Copyright (C) 1991 by Chieh Cheng. All Rights Reserved. No command-line parameters. Syntax: [d:][path]exDEL.EXE [options] [d:][path]filename.ext exDEL is able to accept more than one file specification to delete at a time. Options: -d, D Display files -n, N No display exDEL 1.01 5 Syntax ------ The syntax for exDEL is: [d:][path]exDEL.EXE [options] [d:][path]filename.ext Specifications surrounded by brackets, [], are optional. exDEL will also accept more than one filename.ext. The first [d:] is the drive where DOS could find exDEL. The second [d:] is the name of the disk drive that holds the files(s) to be deleted. For example: C:. The first [path] is the directory where DOS could find exDEL. The second [path] is the directory where the file(s) you want to delete are. For example: \exDEL\. [options] is where you specify the command-line options discussed later. filename.ext is where you specify which files you want to delete. Wildcards (* and ?) are allowed. Examples: *.*, ?f?.*, exDEL.EXE, *.com, etc. Command-line Options -------------------- There are currently only two options: -d, D Display whether files are deleted or if an error had occured. It lists all files found using the file specification. -n, N No display, none at all, just like the DEL command. You may specify both options, but -n have higher priority. Therefore if you specify both, nothing will be displayed. The dash (-) in front of the options could be replaced with a slash (/). For example, -d could be replaced with /d. More options will be added later. exDEL 1.01 6 Rules ----- 1. If you do not give a disk drive name, the current drive will be used. 2. If you do not give a path name, the current directory will be used. 3. If you give drive name and path name, but no file name, exDEL will quit and display "0 file deleted". Unlike the DOS version, exDEL will not assume you mean *.*. 4. Unlike DOS, if you use *.* as file specification, exDEL will not ask "Are you sure (Y/N)?". It will proceed and delete all the files. 5. Current version of exDEL will not let you remove all the files in a directory in your current directly when you type: exDEL dir Future version will. It will also let you remove the directory along with the files. Examples -------- exDEL *.* exDEL -d b:\*.* c:\exDEL\exDEL a:\e??EL.* -d exDEL *.* -n exDEL /n ?xDE????.DOC exDEL *.bat *.sys -d *.bak -n exDEL *.txt /d *.tmp -n exDEL 1.01 7 Error Messages -------------- 1. Permission denied Occurs when exDEL tries to delete a file marked with Read-only file attribute. You must change it with the DOS utility, ATTRIB.EXE, before exDEL could delete it. Future version of exDEL will be able to delete files marked with Read-only and others. 2. No command-line parameters You did not enter any command-line parameters. Refer to the Syntax section. 3. No file specification You did not tell exDEL what files you want to delete. Refer to the Syntax section. 4. Error in command-line options You have made a mistake when typing in options. For example: -d into d or -, -d-n into -dn. Refer to the Command-line Option section. exDEL 1.01 8 Comments from the author ======================== That's about it. Since this is the second release, it would not be as good as it should be. I will try to make it better as soon as possible. As people always said, the programmer who programmed the program will not be a good tester. So I will release this and let you, users, test it. If you find any bugs, inconveniences, or problems in the product just write to us. I would also like to hear your questions, requests, comments, suggestions, or improvements. Just write to: Chieh Cheng 17914 Florwood Ave. Torrance, CA. 90504-3847 FAX (213) 715-6752 CompuServe [73500,244] If you tried this program and thought it wasn't good enough, tell me what's wrong with it and I'll try to improve it. By the way, I will be very grateful if you would send me ideas on what functions I should put into exDEL in later releases. Thanks.
