I've got some files for a project that's due in a few weeks. The guy sent them in a zipx file. How would I extract the files from a zipx on OS X or Linux?

I would really like to. – epochwolf Nov 3 '09 at 22:39

The Unarchiver v2.3 will do, except for compressed jpeg within the zipx archive.

It's up to v3.2 now, and claims full zipx support as of 3.0. – Ron Jul 19 '12 at 19:58

ZipX is an advanced Zip compression format introduced by WinZip. It appears there's only a few commercial utilities that support it.

OSX users can use Stuffit Deluxe 2009 for Mac ($50 USD) to decompress these files. (The claims Stuffit Deluxe can do it, but I actually don't see that specified on the Stuffit site, so look carefully before buying.)

Aside from that, I'd recommend requesting the files in a more standard archive format. Neither RAR nor 7zip archivers support ZipX yet.

comment from David De: Not sure if the demo version is supposed to allow you to extract a zipx file, but it didn't let me. This is on a G4 Powerbook running 10.5.8 – quack quixote May 14 '10 at 11:38
comment from Rbehymer: Just tried Stuffit Expander 2010, no luck expanding a client's zipx file. Client tried opening her own file, had no problems, so corrupt file isn't the problem. Stuffit doesn't seem to be of any help with this. – quack quixote May 14 '10 at 11:39

The winzip evaluation version installed perfectly on wine, and was able to extract the archive for me. (I tried The Unarchiver, but as Kenny noted, it wouldn't extract JPEG files)
