Thanks Hussein for your updates,
when I type zip and enter I get the following lines and version info,
For r12 what should be the minimum zip version?
C:\Documents and Settings\orauser>zip
Copyright (C) 1990-1999 Info-ZIP
Type 'zip "-L"' for software license.
Zip 2.3 (November 29th 1999). Usage:
zip [-options] [-b path] [-t mmddyyyy] [-n suffixes] [zipfile list] [-xi list]
The default action is to add or replace zipfile entries from list, which
can include the special name - to compress standard input.
If zipfile and list are omitted, zip compresses stdin to stdout.
-f freshen: only changed files -u update: only changed or new files
-d delete entries in zipfile -m move into zipfile (delete files)
-r recurse into directories -j junk (don't record) directory names
-0 store only -l convert LF to CR LF (-ll CR LF to LF)
-1 compress faster -9 compress better
-q quiet operation -v verbose operation/print version info
-c add one-line comments -z add zipfile comment
-@ read names from stdin -o make zipfile as old as latest entry
-x exclude the following names -i include only the following names
-F fix zipfile (-FF try harder) -D do not add directory entries
-A adjust self-extracting exe -J junk zipfile prefix (unzipsfx)
-T test zipfile integrity -X eXclude eXtra file attributes
-! use privileges (if granted) to obtain all aspects of WinNT security
-R PKZIP recursion (see manual)
-$ include volume label -S include system and hidden files
-h show this help -n don't compress these suffixes
