PKZIP and PKUNZIP command line utilities for handling zip files, are not the most intuitive. Instead of having to remember the proper command line parameters, for either compressing files into a zip file, or to extract the files again from a zip file, then one can put them in a batch file.

Create a batch file called ZIP.BAT containing the following lines:

@ECHO OFF
REM *** If no parameters then compress all files into ZIPFILE.ZIP
IF "%1"=="" GOTO NONAME
REM *** If one parameter(filename) then compress all files into filename
IF "%2"=="" GOTO ALL

REM *** Both filename to compress to is given and files to compress ***
PKZIP -a -ex -r -P -whs %1 %2 %3 %4 %5 %6 %7 %8 %9
GOTO EXIT

:ALL
PKZIP -a -ex -r -P -whs %1 *.*
GOTO EXIT

:NONAME
PKZIP -a -ex -r -P -whs ZIPFILE.ZIP *.*

:EXIT

Create a batch file called UZIP.BAT containing the following lines:

@ECHO OFF
REM *** If no parameters then extract all the zip files ***
IF "%1"=="" GOTO ALL
REM *** If only one parameter given then extract to current directory ***
IF "%2"=="" GOTO HERE

REM *** Two or more parameters given, the 1st is the zip file, the 2nd is the destination ***
PKUNZIP.EXE -d %1 -o %2
GOTO EXIT

:HERE
PKUNZIP.EXE -d %1 -o .\
GOTO EXIT

:ALL
PKUNZIP.EXE -d *.ZIP -o .\UZIP\

:EXIT
