To be honest I never spend much time to look for a shell solution.
Tough your web site shows how to call winZip using a ShellAndWait call.
WinZip is 32 dollar I believe ( it is worth it)
...
Maybe, maybe not. The combination of tar and bzip2 command line utilities ported
from the Unix world generally produces smaller final archives than WinZip or
equivalents in less time. And both tar and bzip2 are open source and freely
available. But the OP wants Zip files, so gzip would be the freely available,
open source option.
Where's the value proposition for WinZip? If you believe Nico Mak just deserves
business, why? PkWare developed the original PkZip program. Why buy a clone of
the original? If faster & cheaper are legitimate reasons to buy something else,
why settle for WinZip when there are cheaper alternatives that provide
comparable performance? If A and B both perform the same operation in about the
same amount of time, but A costs $32 and B costs $0, which is truly 'worth it'?
Note that PowerArchiver and PkZip both support bzip2 compression. I can't find
any mention of bzip2 on WinZip's web site. bzip2 is the most compact format to
date, so a bit deficient not to support it.
By what objective measure would WinZip be preferred?
