Compression (archiving) programs you prefer/know

[Maz]

I think we should pack all of CWF games with one archiver. That way we need to wrote only on instruction on how to unpack em.

So, I would like to hear which methods do you use / are familiar with. Feel free to write them all in here

Anyways, ones I'll consider must be:

1. good (good compression ratio)
2. free
3. available for multible platforms
4. common.
5. easy to use.

Anyways, if some of these does not apply to your favourite archiver, you can still spill it out I'm anyways interested to know how many of us actually use for example bz2 compression
