What is a good and free unzipping software for Mac?

Good as in...supporting different types of compressed files and can unlock password protected ones.

The built-in one on Mac doesn't do a good job with password protected files.

I'm a big fan of The Unarchiver - it will unpack just about anything and its FREE.

Right now I use 7-Zip a lot, since it has multi-threading support and can maximize my CoreDuo, but Unarchiver is great as a swiss army knife unpacker.

I think the Unarchiver is the best option here. – Bryan Schuetz Jul 31 '09 at 3:18
Me too. After going through some of suggestions, Unarchiver solves my pain most easily and efficiently. – codingbear Jul 31 '09 at 21:11

FWIW, unzip at the command line is built in and works pretty well. To use it with a password it's:
unzip -P PASSWORD_HERE path/to/zip/

Somehow 7-zip hasn't made it onto my system, but it is a great one.

What has made it on however is unrarX and Stuffit Expander. Stuffit isn't exactly great but it is required for some of the old legacy compression formats.

7-zip has a Mac port called p7zip. Another one called EZ 7z is the same principle but has a nicer interface.
