ADDENDUM to PKZIP 2 Manual -------------------------- This file contains the most up-to-date information, additions and changes to the PKZIP version 2 manual. AUTHENTICITY VERIFICATION FEATURE --------------------------------- The Authenticity Verification information you receive from PKWARE will include two AV Serial Numbers and one checksum. The Serial Numbers and checksum include BOTH letters and numbers. ALL LETTERS are LOWER CASE, with the exception of the letter L. The letter L will be printed in upper case to avoid confusion with the number one. After both Serial Numbers are entered using the PUTAV.EXE, the program will return a checksum value. This checksum must match the one provided by PKWARE. If the checksums do not match, then the installation was not performed correctly and PUTAV.EXE should be run again to ensure that the Serial Numbers and Name were entered correctly. If you run PUTAV.EXE and you encounter the error, "WRONG VERSION OF PKZIP.EXE", verify that you are running PUTAV on the REGISTERED version of PKZIP.EXE. AVEXTRA.TXT ----------- With the PKZIP 2 Authenticity Verification feature, additional text can be displayed on subsequent lines following the verification message. An ASCII text file named AVEXTRA.TXT is created containing the additional text you want displayed. When the AVEXTRA.TXT file is in the current directory when you use the "PKZIP -!" option, PKZIP will add this text to the .ZIP file and PKUNZIP will display it after the normal Authenticity Verification message. The Authenticity Verification feature is available only to registered users of PKZIP. SELF-EXTRACTING FILES ACROSS MULTIPLE DISKETTES ----------------------------------------------- PKZIP 2 has the ability to compress a large .ZIP file across multiple diskettes. Self-extracting files CAN NOT span multiple disks. This would make the PKSFX code extremely large. A simple batch file can be created that would uncompress across multiple diskettes. All that would be required is to have the batch file follow this procedure: 1. Create a batch file called install.bat 2. Edit install.bat and in that file have the following line: pkunzip -d a:program c:\test This batch file would create the directory C:\TEST on your computer and then unzip the file called PROGRAM.ZIP into the c:\test directory. PKUNZIP will prompt the user to enter the diskettes in the extraction order. PKCFG.EXE --------- * PKCFG.EXE is only included in the registered version of PKZIP. PKZIP.EXE can have many of its features configured with a configuration file called PKZIP.CFG. This configuration file can be located in either your current directory, a directory specified with the environment variable PKZIP.CFG, or in the directory that PKZIP.EXE is located. PKZIP.EXE will search for the configuration in each location in the order listed above. This means that you may have a default configuration file that is easily overridden by using a configuration file in either of the first two locations. Any option that is set in the configuration file may be overridden from the command line. The configuration file may be created manually with a text editor. The PKCFG.EXE program will look for an existing configuration file in the same locations and order that PKZIP.EXE would look. If the PKCFG.EXE program finds an existing configuration file it will load it. The existing configuration values will be shown in the place of the defaults. A list of options will be displayed on the screen, and a highlighted cursor indicates the option that you can modify. PK SAFE ANSI ----------- * PKSFANSI.COM is only included in the registered version of PKZIP. Another program included with registration of PKZIP 2 is called PKSFANSI.COM. PKSFANSI is a terminate and stay resident program that disables ANSI keyboard key Reassignments, thereby preventing ANSI "bombs" embedded in any text file (such as README files) or output by any program. Normally, ANSI sequences that redefine the keyboard could be hidden inside ANY text file or program, and could be executed completely unnoticed until it is too late. PKSFANSI intercepts calls to the ANSI.SYS or other ANSI device drivers, and filters out any keyboard reassignments, while allowing other ANSI sequences through unaltered. If a keyboard reassignment is attempted, PKSFANSI will intercept the sequence and discard it. PKSFANSI will also BEEP to alert you that a reassignment was attempted. PKSFANSI requires less than 1K bytes resident RAM, and should work with any ANSI driver, such as the standard ANSI.SYS driver, NANSI, ZANSI, DVANSI, etc. Note that if you use a memory resident ANSI driver, such as the DESQview DVANSI.COM driver, PKSFANSI should be loaded after the ANSI driver is loaded. Using PKZIP and DPMI -------------------- If you experience difficulties when using PKZIP in a DOS window under Windows, use the -) option to disable DPMI support. If this eliminates the problem, you may default this option for PKZIP by using the configuration file (see manual for details). With PKUNZIP, this option may be set as an environment variable (see below for details). PKUNZIP as an Environment Variable ---------------------------------- PKUNZIP includes the ability to use an environment variable as a continuation of the command line. An option, or number of options may be specified by an environment variable. PKUNZIP will treat the variables as if they were passed on the command line. example: set PKUNZIP=-) This example would disable DPMI usage. Note that since the PKUNZIP environment variable is a continuation of the command line; it will supersede any preceding option on the command line. Minimum DOS Requirements for SPANNING & FORMATTING -------------------------------------------------- For PKZIP 2 to span multiple disks with a .ZIP file, DOS 3.0 or greater is required. To be able to format diskettes on-the-fly, DOS 3.2 or greater is required. PKUNZJR.COM & PKSFX Junior -------------------------- When using PKUNZJR or PKSFX Junior, remember to end your output path with a : or a \. Because the PKUNZJR and PKSFX Junior were designed to be as small as possible, please note that they perform minimal error checking. CHANGE TO "MOVE" OPTION ----------------------- When using the -m option in PKZIP.EXE PKZIP will now remove the directories and subdirectories after the compression process has been completed. This feature is turned on by default. If you wish PKZIP not to remove the directories/subdirectories, use a -m- option to disable this feature. PKNOFASTCHAR= Environment Variable --------------------------------- This tells PKZIP/PKUNZIP to use the slow DOS 1.x/2.x character output function calls rather than the 'DOS Fast Character Output' function. This option is designed for compatability with TSR's or BBS doors etc. that do not intercept the DOS Fast Character Output function. ERROR MESSAGES -------------- This is an addendum to the ERROR MESSAGES found in the manual. PKZIP: (E[19-23] and E29) Insufficient Memory PKZIP: (E26) DOS 3.0 or later needed to span disks PKZIP: (E26) DOS 3.2 or later needed to format disks PKZIP: (E28) Destination for .ZIP file is same as temporary file PKZIP: (E28) Source and destination is the same PKZIP: (W07) Warning! Bad System Track PKZIP: (W08) Warning! Can't write FAT PKZIP: (W09) Warning! Can't write root directory PKZIP: (W10) Warning! Can't write boot sector ZIP2EXE: (E09) Can't create ouput file ZIP2EXE: (W01) Warning! The file already exists, overwrite (y/n)? PKSFX: Warnings numbers are the same as PKUNZIP [9-18,20,21,23,24] PKSFX: (E02,E03) Error in .EXE file PKSFXJR: No numbers are printed by PKSFXJR. The manual states that PKSFXJR will report error numbers, but this is incorrect. It will print only a message, no number is printed. The errorlevel will be returned to DOS however. SUMMARY ------- PKZIP: 0 No Error 1 Bad file name or file specification 2,3 Error in .ZIP file 4-11 Insufficient Memory 12 No files were found to add to the .ZIP, or no files were specified for deletion 13 File not found.

(help screen displayed) 17 Too many files 18 Could not open file 19-23,29 Insufficient Memory 26 DOS 3.2 or later needed to span disks 28 Destination for .ZIP is same as temporary file or Source and destination is the same 255 User pressed control-c or control-break ZIP2EXE: 0 No error 1 Error in .ZIP file 2 Error in .ZIP file, use PKZIPFIX 3-4 Insufficient memory to process file 6 Bad or illegal parameters specified. (help screen displayed) 7 Can't open Source file 8 Error in .ZIP file 9 Disk full writing target file during EXE to ZIP process 11 Disk full writing target file during ZIP to EXE process 12 .ZIP file being converted contains a file compressed with a method not supported by the version of PKSFX being attached by ZIP2EXE 13 User answered "No" in response to an "overwrite(y/n)?" prompt PKSFX: 1 Warning error such as: File fails CRC check, Unknown compression method. 2,3 Can't find .EXE file 4-8 Insufficient memory 9 Unable to locate listfile 10 Bad or illegal parameters specified. (help screen displayed) 12 User aborted at comment pausing, "Extract now (y/n)?" prompt 2,3,13 Error in .EXE file 50 Disk full NOTES ----- Note, the -x option in PKUNZIP now is used to specify files to eXclude. As stated in the PKUNZIP 1.1 documenation, use of '-x' to mean eXtract would not be supported in future versions of PKUNZIP. The -e option of PKUNZIP specifies extraction. Note, the -o and -k, as well as the ZIPDATE= options in the pkzip.cfg file, will be ignored when used with the -& option. Note, PKZIP requires 206K of memory if no EMS or XMS is available, and 108K if enough EMS/XMS is available. Note, In the PKZIP manual, it states that the -o option will set .ZIP file date to oldest file in .ZIP file. This should read set .ZIP file date to latest, not oldest. Note, Page 76 of the PKZIP manual incorrectly lists the default value of view as Long. The default value of view is normal. Note, When using either the -&l or -&u, both of these options will format the destination diskette(s). PKZIP BACKUP GUIDE ------------------ PKZIP can now create .ZIP files that exceed the size of a floppy disk. You can use PKZIP to backup your entire hard disk and unlike most backup programs, PKZIP can use disks formatted by DOS, or it can format the disk for you. PKZIP can optionally erase all files on the destination disk(s), or leave those files intact. PKZIP can optionally quick format the destination disk(s), or do a normal (unconditional) format. A quick format erases the information on the disk without formatting each track, greatly reducing the time required to format a disk. Option Description -------------------------------------------------------------------- -& Span disks if necessary. You must specify this option if you wish to create a .ZIP file on multiple disks. If this option is not specified and you exceed the capacity of a floppy disk, a DISK FULL error message will result. -&f Format the destination disk. PKZIP will format the destination disk(s) if you specify this option. If the disk has been formatted previously, a quick format will be performed, otherwise a full format will be performed. -&fl The destination disk is to be formatted to low density. If you plan to use low density disks in a high density disk drive, this option is required. For example, if you have a 1.44 meg floppy disk drive, and plan to zip to 720K disks and your disks are not formatted, you must specify this option. If your disk drive is a 360K or 720K drive, this option is not required. If any information was previously contained on the disk, it will be erased. -&u Unconditionally (always) format the disk. Always format the disk before being used. A full format will be used, a quick format will never be performed. If any information was previously contained on the disk, it will be erased. -&ul Unconditionally (always) format a low density disk in a high density disk drive. Always format the disk before being used. A full format will be used, a quick format will never be performed. If any information was previously contained on the disk, it will be erased. -&w Wipe the disk. (Erase all files and subdirectories) This is similar to -&f, except the files are deleted, rather than formatting the disk. This is for usage with non floppy removable devices, such as Bernoulli boxes. -&s[d:] Include subdirectories in zipping process (similar to -rp \*.*). -&v Turn on DOS verify when spanning. This may also be set by using BACKUP=verify in the pkzip.cfg file. This option tells PKZIP that you wish to backup the entire disk drive. The current disk drive will be used if no disk drive is specifed. You do not need to specify the -rp option (recurse and store pathnames). If you also specify files on another disk drive, these files will be compressed, as well as all files on the default drive. (Please see following examples.) All options are case insensitive, but this may change in future versions. We suggest you USE LOWER CASE LETTERS FOR FUTURE COMPATIBILITY. The -&l option must be specified with -&u or -&f. * Note: If you create a .ZIP file with the same name as exists on a disk set, you do not need to use the WIPE or FORMAT options. PKZIP will create a new .ZIP file with the same name; this method is faster. * Note: All the PKZIP Configuration File options can be overridden on the command line by specifying the option and a '-'. For example, -&f- will override "BACKUP=FORMAT" in the Configuration File and turn off formatting. * Note: When using PKUNZIP.EXE to restore a from a spanned backup set, it is most efficient to start by inserting the last diskette. * Note: If you would like to use PKZIP.EXE for full and incremental backups, use the -a+ for the full backup. This will turn off the archive attribute after the files have been compressed. Then to perform a incremental backup, use the -i option. This will compress only files that have changed since they were last backed up. Examples -------- Command Line Description ----------------------------------------------------------------- pkzip a:zipfile -& Zip the current directory to drive A:, and span disks if necessary. The files currently on drive A: will not be affected. C:\>pkzip a:zipfile -&s Zip all files on drive C: to the A: drive. C:\>pkzip b:zipfile -&s d:\sd\*.* Zip all files on drive C: (the current drive), and all files in the D:\SD directory to the B: drive. C:\>pkzip a:zipfile -&s d:\*.BAT Zip all the files on drive C: and all .BAT files on drive D: to the A: drive. pkzip a:zipfile -&f -rp Zip the current directory and its subdirectories to drive A:, and format each disk. A quick format will be performed if possible, which is much faster than a unconditional format. pkzip a:zipfile -&u -rp Same as above, except the disk will be unconditionally formatted. pkzip a:zipfile -&fl Zip the current directory to drive A:, and format each disk to low density. This option only applies to users using a 360K floppy disk in a 1.2 meg drive, or users using a 720K floppy disk in a 1.44 meg drive. A quick format will be performed if possible, which is much faster than a unconditional format. pkzip a:zipfile -&ul Same as above, except the disk will be unconditionally formatted (do not quick format). pkzip a:zipfile -&w -rp Zip the current directory and its subdirectories to drive A:, and wipe each disk. All files and subdirectories will be erased from the A: drive. The disk will not be formatted or quick formatted. pkzip a:zipfile -&fs Zip the current disk drive (including subdirectories) to drive A:, and format each disk. If the destination disk has previously been formatted, a quick format will be performed. Otherwise, an unconditional format will be performed. New Options For the PKZIP.CFG Configuration File ------------------------------------------------ The keyword BACKUP= can be followed by the following keywords: SPAN The -& option is enabled. If this keyword is not specified, the following options will only be enabled when -& is specified on the command line. Same as -&. UNCONDITIONAL Format the disk unconditionally. Same as -&u. LOW Using low density disks. Same as -&l FORMAT Format the disks. Same as -&f. WIPE Wipe the disks. Same as -&w. FULL Do a full backup. Same as -&s. VERIFY Turn on DOS verify when spanning. Same as -&v Examples Same as -------------------------------------------------------- BACKUP=SPAN FORMAT -&f BACKUP=SPAN FORMAT UNCONDITIONAL -&u BACKUP=LOW VERIFY SPAN -&lv BACKUP=FORMAT WIPE Illegal -- WIPE and FORMAT are exclusive.
