ZIPALL Version 1.2 Freeware by Michael K. Davis Freespace: the final frontier. ZIPALL is just a collection of .BAT files I wrote to continue on where PKWARE left off. They exploit PKZIP and PKUNZIP in a BIG way! Read on: WHAT DO THESE .BAT FILES DO? They negate the need for whole-drive compression products that slow down your system, consume RAM, and enslave your files to a mysterious, proprietary, virtual nowhere. They put YOU back in control of your data! -- SPEED! Your applications will execute from files that are fully decompressed before the applications even start. -- MEMORY! No additional TSR's or device driver's eating your RAM. -- CONTROL! You decide what's compressed, one application at a time. Restore to "normal" whenever you want. -- SIMPLICITY! Three commands to learn: ZIPALL, UNZIPALL & RESTZIP These commands don't even have switches - no syntax to remember! One command to compress an entire application. One command when you're ready to use it. One command when you're finished using it. -- ERROR RECOVERY! Accidentally delete a file, alter a file, "die" in your favorite action game when you were just about to reach the highest level! --> NO PROBLEM... We're talking about the ultimate UNDO here! HOW DO YOU USE THESE .BAT FILES? Put the efficient and reliable PKZIP and PKUNZIP to work to compress entire applications, including children subdirectories, if any, into individual .ZIP files named ALLFILES.ZIP. You do this to your choice of any applications on your system by simply executing "ZIPALL" at the parent directory of each. (No complicated syntax here; it's real simple!) Later, when you want to use an application, just CD to that same directory and say "UNZIPALL" to restore the original files and children subdirectories! Then start your application as usual. (No complicated syntax here, either!) When you finish using the application, just CD to it's parent directory and issue "RESTZIP". It will remove the children subdirectories, if any, and delete all the files except for ALLFILES.ZIP, after giving you a choice of whether or not to update ALLFILES.ZIP with files that have been changed or added while using the application. It even shows you what files have been changed or added before asking you to decide! (No complicated syntax here! Let my .BAT files do the thinking!) Automate the process of decompressing, running and re-compressing an application by writing simple .BAT files like this: C: --> goes to the application's drive CD C:\WP51 --> goes to the application's parent directory CALL UNZIPALL --> decompression before starting the application WP --> starts the application CALL RESTZIP --> re-compression after using the application WHAT ARE THE ADVANTAGES? When you try it you're going to fall in love with it. It's non-invasive. Just run it against a couple of your applications, to get the feel for it. Pay attention to your freespace before and after! There's no virtual bull. CHKDSK will be giving you real numbers! You'll have a REAL hard disk and when you make changes to your AUTOEXEC.BAT or CONFIG.SYS you'll know you've altered the real thing and not some virtual image. When you're in an application, there is no compression product running in the background -- you're running on the real drive without the RAM consumption and loss of speed associated with mysterious virtual drive products. PKZIP is as tight a compression as anyone could hope for. You only have to suffer a "wait-while-it-works" during the initial compression of an application. Later, when you go to use an application, you have to wait a few moments while it decompresses, but remember that once you've started the application, it's running off of fully decompressed files and you haven't added another hog TSR to your conventional memory. When you run RESTZIP, after using an application, it restores in a flash --> only files that have been changed or added are processed! RESTZIP is terrific for recovering from accidents, too. Just exit the application and run RESTZIP selecting "N"o changes, when asked. Then run UNZIPALL again to decompress the whole application to the way it looked before you started (and goofed)! WHAT ARE THE REQUIREMENTS? These batch files require PKWARE's PKZ204G (not included) or later versions. Note: PKZ204C will work, but it has lot's of buts that are fixed in PKZ204G! Also: MS-DOS 5.0, or later, and PATRI-SOFT's PDEL and PATTR, (included). My batch files are freeware, as are two programs I wrote, WHICHWAY.EXE and FEED.EXE, but PKWARE and PATRI-SOFT products are Shareware - please register with their authors. You'll only need as much freespace on your drive as these files consume, and about half as much space as the the first application you decide to compress. The freespace will only increase from then on. HOW DO YOU INSTALL? 1) All the files you unzipped from ZIPALL10.ZIP (my distribution file) should be located to a directory of your choice that is in the PATH statement of your AUTOEXEC.BAT. PKWARE's PKZ204G (or later version) should also be in the PATH statement. (Why not put them both in a directory called C:\PKWARE?) 2) If you have chosen to locate my files in a directory called C:\PKWARE, you are in luck because you won't have to do the following edit!: RESTZIP.BAT and ZIPALL1.BAT must be edited to change all occurrances of the string "c:\pkware" to the drive and directory you've chosen. This string occurs in an instruction that reads: "copy c:\pkware\zipall1.usd" so .... you have to put ZIPALL1.USD in C:\PKWARE or do the editing to indicate where it is... your choice! 3) Now just boot the machine so that my files and PKWARE's are in the PATH. 4) Installation completed. HOW DO YOU START CREATING FREESPACE? CD to the parent directory of any application you want to compress and bravely execute ZIPALL. [Come on in... the water's nice!] Ok, run your backup program first, if you want to. Note the before and after freespace as you go. Don't run ZIPALL on your DOS directory, other directories that are in your PATH, and certainly not in the Root directory of the drive you boot from!!! Use UNZIPALL to decompress an application previously compressed with ZIPALL and then run the application. When you exit the application, run RESTZIP to restore ALLFILES.ZIP, deleting the application's files and removing children subdirectories, if any (recapturing the freespace.) Explore some of the other .BAT files I've written. Some are documented below, but all are well documented within. HOW DO YOU AUTOMATE THE DECOMPRESSION AND RE-COMPRESSION OF APPLICATIONS? To automate Decompression, Use and Re-compression of applications on your disk: 1) Pick an application you'd like to compress and identify it's "parent" directory -- the one closest to the drive's root directory. 2) Identify the startup command normally used to start the application. 3) Using the DOS CD command (ie: "CD C:\WP51") position yourself in that directory. 4) Execute ZIPALL.BAT (ie: "ZIPALL"). This will reduce the current directory and all of it's children subdirectories, if any, to a single file, ALLFILES.ZIP. Don't worry, in four years, I've never seen a bug! Your data is safe! But I make no warranties, and your use of these batch files is at your own risk. 5) If you don't already have one, create a "command directory" that is specified in your AUTOEXEC.BAT's PATH statement. This directory will contain .BAT files which can then be executed from any DOS prompt. (ie: "MD C:\WORK" and add ";C:\WORK" to the AUTOEXEC.BAT's PATH stmt.) 6) Write a .BAT file for this directory for each application you intend to compress. It will look something like this: Don't code these comments in BAT files: @ECHO OFF REM THIS IS C:\WORK\WP.BAT REM C: Changes to C: drive (where the application is) CD C:\WP51 Changes to Application's main directory CALL UNZIPALL * Calls UNZIPALL.BAT to decompress ALLFILES.ZIP C:\WP51\WP Executes the Application's startup command CD C:\WP51 Changes to Application's main directory CALL RESTZIP Calls RESTZIP.BAT to Re-compress ALLFILES.ZIP ECHO ON Resets ECHO to ON and displays RESTZIP msgs. * ALLFILES.ZIP, has been previously created by executing ZIPALL.BAT against this same directory to compress all of the application's contents into the single file. Use ZIPALL1 instead of ZIPALL if there are child sub- directories that you don't want to include. If you use ZIPALL1.BAT, remember to execute UNZIPALL against every ALLFILES.ZIP before attempting to start the application and run RESTZIP.BAT against every ALLFILES.ZIP after exiting the application. 7) Now, you can just say "WP" to execute WP.BAT from anywhere on your system to Decompress the application, start the application, and then Re-Compress the application when you exit it. Note: Your must reboot your machine after making changes to your AUTOEXEC.BAT if you want them to be executed. [Duh...] DESCRIPTIONS OF THE MOST FREQUENTLY USED .BAT FILES: (See comments inside any .BAT for more details.) Name Function ZIPALL.BAT Executed at any DOS prompt, it will compress every file within the current subdirectory AND any child directories beneath it (including Hidden, System, and Read-only files) into a single file called ALLFILES.ZIP, deleting all the original files and removing any child subdirectories. This file must be unzipped with UNZIPALL.BAT or PKUNZIP.EXE using the "-d -Jhrs" switches. UNZIPALL.BAT Executed at the DOS prompt of a directory containing the file ALLFILES.ZIP, it will decompress the ZIP file, recreating the original files, including any that came from child subdirec- tories. It does NOT delete ALLFILES.ZIP. The DOS Archive attributes are turned off every file after decompression. RESTZIP will check these bits to advise you if any files were changed or added at the time you are ready to re-compress. RESTZIP.BAT This is executed at the DOS prompt of a directory containing ALLFILES.ZIP and the decompressed contents of that ZIP file. It deletes all the decompressed files and restore ALLFILES.ZIP as the only file in the subdirectory. If changes were made to the files since ALLFILES.ZIP was decompressed by UNZIPALL.BAT and you want to keep these changes, you will see a list of those changed (or added) files when RESTZIP is executed and you can reply with a "U" to update ALLFILES.ZIP with the changed versions when prompted. Replying "N" will make no changes to ALLFILES.ZIP. RESTZIP.BAT is much faster than re-execution of ZIPALL1.BAT and if you are using a BACKUP utility that does incremental updates to a backup diskette pool, RESTZIP.BAT prevents unneccesary backup of the ZIP file by using the MS-DOS ATTRIB command to turn off the Archive bit when no changes were made. If changes WERE made to ALLFILES.ZIP, it's Archive bit will be turned on, making it elligible to your incremental backup program, if any. ZIPALL1.BAT Executed at any DOS prompt, it will compress ONLY files within the CURRENT subdirectory (including hidden and system files) into a single file called ALLFILES.ZIP, deleting all original files. Children subdirectories are unaffected. This can be run against every subdirectory of a single application (the parent and all it's children), one at a time, if you want to segregrate your control. Compression density will be the same, but UNZIPALL and RESTZIP will have to run against each individual subdirectory, before and after executing the application. If ZIPALL1.BAT is used, a marker file, named ZIPALL1.USD is left in the directory, alongside ALLFILES.ZIP, as a guide for RESTZIP's execution. It will prevent RESTZIP from acting upon child subdirectories when ZIPALL1 was used to process only the current directory. ZIPALLT.BAT This functions just like ZIPALL.BAT with the exception that it DOES NOT delete the original files that were compressed to create ALLFILES.ZIP. This allows you to create a (T)emporary ALLFILES.ZIP for the purpose of copying the contents of the current subdirectory (and its child directories) to another location in compressed format. The recipient must have these these .BAT files installed to use UNZIPALL or may simply issue: "PKUNZIP ALLFILES -d -Jhrs" to reconstruct the original tree structure and retain file attributes. If the recipient does not have PKZ204 and/or these .BAT files, use ZIPEX.BAT instead. (See ZIPEX below.) ZIPALL1T.BAT This functions just like ZIPALLT.BAT with the exception that i acts against only the current subdirectory and ignores children subdirectories. ZIPEX.BAT This functions just like ZIPALLT.BAT with the exception that it leaves you with ALLFILES.EXE (a self-extracting version of the ALLFILES.ZIP that ZIPALLT.BAT would produce). Like ZIPALLT.BAT, the original files remain intact. Any DOS user can execute ALLFILES.EXE to decompress the original directories and files. ALLFILES.EXE must be executed with the "-d -Jhrs" switches: "ALLFILES -d -Jhrs" to build directories and retain attributes. WHAT'S NEW IN VERSION 1.2? Added "attrib -h -s -r *.*" instruction ahead of all occurences of calls to Patri-Soft's PDEL.EXE. It does not delete files with the Readonly attribute unless they are in a subdirectory of the current directory! The change makes it possible for PDEL to cleanup the directory as intended after ALLFILES.ZIP is created or updated. WHAT WAS NEW IN VERSION 1.1? Added check to stop execution of ZIPALL.BAT when PKZIP returns a non-zero errorlevel after trying to create ALLFILES.ZIP. Handles situations like insufficient space on the drive to create the ZIP file. Made similar change to the Update routines within RESTZIP.BAT, when it's trying to update an existing ALLFILES.ZIP. Added warning notes to this doc file regarding use of PKZ204C. (Use PKZ204G or better, instead.) Enjoy, Michael K. Davis I'm not going to tell you where I live, because no one would register this if it were shareware instead of freeware, anyway! P.S.: Don't send me any money. [Duh...]
