Instructions on using PKZIP and PKUNZIP
This instruction page gives brief instructions on using PKZIP and PKUNZIP for compressing and decompressing file respectively. If you don't have the software, click here to download the self-extractable file. It is recommended the file be save in the C:\Windows folder.
Since pkz204g.exe is a self-extractable file, you can locate the file (in C:\Windows) and double click it to extract or decompress the file.
To use PKZIP and PKUNZIP, you need to open a DOS prompt in Windows environment. The following gives the syntax of using PKZIP and PKUNZIP and examples of using the software:
To compress files, use PKZIP as shown in the following:
Usage: PKZIP [options] zipfile [@list] [files...]
Simple Usage: PKZIP zipfile
file(s)...
| | |
Program -----------------
| |
| |
New zipfile to create ---------- |
|
File(s) you wish to compress ----------
The above usage is only a very basic example of PKZIP's capability.
The options are as follows:
-a
Add files
-b[drive] create temp zipfile on alternative
drive
-d
Delete files
-e[x,n,f,s,0] use [eXtra|Normal (default)|Fast|Super fast|NO
compression]
-f
Freshen files
-l
display software License agreement
-m[f,u] Move files [with Freshen |
with Update]
-u
Update files
-p|P store
Pathnames|p=recursed into|P=specified & recursed into
-r
Recurse subdirectories
-s[pwd] Scramble with password [If
no pwd is given, prompt for pwd]
-v[b][r][m][t][c] View .ZIP [Brief][Reverse][More][Technical][Comment] sort by
[d,e,n,o,p,s] [Date|Extension|Name|natural Order(default)|Percentage|Size]
-&[f|l|u Span disks [Format|format
Low density|Unconditional format|
ul|w|v] Unconditional Low density|Wipe disk|enable dos Verify|
[s[drive]] Back up entire disk w/ subdirs (-rp) [drive to back up]]
-a+ clear archive Attribute after
compression
-c create/Edit Comments for
all files
-C add Comments for new files
only
-i[-] add files with archive Attribute set
[don't turn attribute off]
-j|J<h,r,s> mask|don't mask <Hidden/System/Read-only> files
(default=jhrs)
-k Keep original .ZIP file
date
-o set .ZIP file date to the
latest file in .ZIP file
-q enable ANSI codes in
comments
-t[date] take files NEWER than or EQUAL to date (default=today)
-T[date] take files OLDER than date (default=today)
-w|W<h,s> include|exclude <Hidden, System> files
(default=Whs)
-x<file> eXclude specified file
-x@list eXclude file(s) in specified list file
-z create or modify .ZIP
comment
-! add authenticity
verification to .ZIP file (registered vers only)
-$[drive] save Volume label in .ZIP file (default = current drive)
-@list generate list file
-= open file in compatibility
mode (bypass share)
-3 Disable 32-bit instruction
usage on 80386 or higher CPU's
-^ Echo the command line
-+ Disable Expanded Memory
(EMS) usage
-- Disable UMB/HMA Memory
(XMS) usage
-~ Disable Network usage
-) Disable 32 bit DPMI usage
-( Use "Slow"
MemCopy
Usage: PKUNZIP [options] zipfile [@list] [files...]
-c[m]
extract files to Console [with More]
-d
restore/create Directory structure stored in .ZIP file
-e[c|d|e|n|p|r|s] Extract files. Sort by [CRC | Date | Extension | Name
| Percentage | Reverse | Size]
-f
Freshen files in destination directory
-j|J<h,r,s> mask|don't mask
<Hidden/System/Readonly> files (def.=jhrs)
-n
extract only Newer files
-o
Overwrite previously existing files
-p[a/b][c][#] extract to Printer [Asc mode,Bin mode,Com
port] [port #]
-q
Enable ANSI comments
-s[pwd] Decrypt with
password [If no pwd is given, prompt for pwd]
-t
Test .ZIP file integrity
-v[b][r][m][t] View .ZIP [Brief][Reverse][More][Technical] sort
by [CRC|
[c,d,e,n,o,p,s] Date|Extension|Name|natural Order(default)|Percentage|Size]
-x<filespec> eXclude file(s) from extraction
-$
Restore volume label on destination drive
-@listfile Generate list file
-- TROUBLE SHOOTING OPTIONS --
-3 Disable 32-bit instruction usage on 80386 or
higher CPU's
-^ Echo the command line
-+ Disable Expanded Memory (EMS) usage
-- Disable UMB/HMA Memory (XMS) usage
-) Disable 32 bit DPMI usage
1. To compress file(s) into a zipped file on A disk.
PKZIP A:\TEST.ZIP C:\TEMP\TEST1.TXT C:\TEST2.TXT
where TEST.ZIP to be stored on the floppy in A drive is the target file after compression. It contains both TEST1.TXT in the C:\temp\ directory and TEST2.TXT on C: root directory.
2. To compress multiple files including the subdirectories.
PKZIP -pr TEST.ZIP C:\TEMP\*.*
where TEST.ZIP is the compressed file that contains all files with subdirectories under C:\TEMP\ directory.
3. To compress files onto multiple diskettes.
PKZIP -& a:\TEST.ZIP C:\TEMP\*.*
where TEST.ZIP is bigger than one floppy diskette can hold (1.44 mb). For example, consider you have a 5 mb file. Even after compression, the zipped file will be more than 2 mb. You need to use this method to compress the file onto multiple disks.
4. To view contents of zipped file
PKUNZIP -v TEST.ZIP
5. To decompress files:
PKUNZIP A:\TEST.ZIP C:\TEMP
where TEST.ZIP will be decompressed into C:\TEMP directory.
6. To decompress files in subdirectory:
PKUNZIP -d A:\TEST.ZIP C:\TEMP
where TEST.ZIP is created using the -pr option and contains subdirectories and
files.
(*) To download the files, hold down the shift key and click on the link.
