The Java 'jar' tool supports a subset of ZIP's capabilities, and ships
with IBM i. In my experience, it's klunky and slow, but it works. Example:
jar cMf /tmp/output.zip /mydir/*.txt
The InfoZip tools (the ones included with most Linux/Unix systems) are
free and available for PASE (under IBM i). It supports most features of
Zip files, but only supports weak encryption (like the earlier Zip
programs did.) This used to be my favorite way of making Zip files
(until 7-Zip):

The preceding article refers to a site called AIXPDSLIB from UCLA. It
no longer exists, but you can still get the code here:

The 7-Zip tool supports Zip as well as many other archive formats, and
also supports stronger encryption. It's open source (free) and
available for PASE. I've posted a copy on my web site:
http://www.scottklement.com/p7zip
There have been several discussions about 7-Zip in the archives for this
mailing list, as well as System iNetwork's forums. If you run into
questions/problems, searching the archives for those sites might provide
the answers.
A Japanese programmer named Hideyuki Yahagi (better known as Uzaemon)
has ported MiniZip/ZLib as native (non-PASE) tools. He has them
available as a free download on his site:

Finally PKWare (the company that owns the original PKZip software) has a
commercial (for money) ZIP offering for i5/OS.

So there you have 5 possible solutions.
When this question has been asked in the past, some people have
mentioned TAR and GZIP as possibilities as well. Although these
solutions work great, they are _not_ for .ZIP format, they have their
own file format. If you are exchanging data with someone else you won't
want this. But if you're just archiving data for your own purposes,
these might offer a 6th possibility.

Is there any ZIP (compression) freeware available on the iSeries platform? If
so, can I get some opinions on which ones are the most practical. Thanks!
