- Scott,
-
- Taken directly from the manual for ZIP for OS/2:
-
- DESCRIPTION
- zip is a compression and file packaging utility for Unix,
- VMS, MSDOS, OS/2, Windows NT, Minix, Atari and Macintosh.
- It is analogous to a combination of tar and compress and is
- compatible with PKZIP (Phil Katz ZIP) for MSDOS systems.
-
- There is a companion to zip called unzip (of course) which
- you should be able to find the same place you got zip. zip
- and unzip can work with files produced by PKZIP under MSDOS,
- and PKZIP and PKUNZIP can work with files produced by zip.
-
- zip version 1.9 is compatible with pkzip 1.93a. Note that
- pkunzip 1.10 cannot extract files produced by pkzip 1.93a or
- zip 1.9b. You must use pkunzip 1.93a or unzip 5.0 to extract
- them.
-
-
- Perhaps I did not state it well - as mentioned above, ZIP works fine
- with PKZIP files. However, earlier versions of PKZIP were not fully
- compatible with ZIP'd files from other sources. Since your Apple and
- Unix boxes used ZIP (since PKZIP is an MSDOS program), I am sure there
- was no problem with passing files back and forth. However, PKZIP in
- the MSDOS world was one of the first and is the largest used compression
- program today. Since it will not always handle files compressed with
- ZIP, an upgrade to the latest version is in order to maintain complete
- compatibility across platforms. And that is what the original poster
- was asking.
