Zip is totally useless - it can't really compress if matched against
the latest archiving tools.
A cross-platform (and the best next to lzma) solution would be RAR,
but you may not like its licensing implications.
.xz and .7z may not be the same (compressed vs. archived?), but the
7zip client is able to uncompress .xz from beta version onwards. Linux
users can unpack anything, so in the end I don't see why you couldn't
just go .7z and hjsplit/lxsplit the result to 4 parts to be even more
friendly.

I think this is the best bet for windows and OSX is mentioned there as
well. I think .7z and .xz isn't the same, and .xz is certainly quite
new. .7z isn't that common on linux.
It's kind of hard to say what to use.. most compatible would be .zip I
think, .xz might offer the best compression ratio and .bz2 is somewhere
in between, supported by 7zip and winrar (both common on windows in my
experience). I don't know about OSX.
Since only betas of 7zip come with .xz support I'd go with .bzip2 and
maybe compare to .zip to see whether it's worth it. Excerpts from torbenh's message of 2010-03-31

That's more what I was thinking, bzip or lzma, How well supported are
these on windows or osx? I haven't used win for 6 years or so.. On Wed, Mar 31, 2010 at 09:04:10AM -0700, Kevin

i know, that flac only compresses .wav
its a .gig file.
not sure if wavpack compresses arbitrary binaries.
Well, wavpack is also designed for lossless audio. If the whole .gig is
compressed as such then I'd use a generic format, maybe .xz aka. lzma2.
wavpack only has 'raw-pcm' options which obviously refer to pcm data.
I don't know how .gig works and whether the samples and the
meta-information can be split/joined easily. Probably not worth the
trouble.
