Entropy | Mac Os X | 8.9 MB

Easily create, open and preview popular archive files like ZIP, RAR, 7z, TGZ and more ( 30+ formats supported ). Entropy has been designed specifically for your Mac. It supports OS X specific technologies like extended file attributes and resource forks, which are often missing in other archives. Entropy directly reads and writes archives, unlike most other archivers for Mac which are simply "front-ends". The end result is that Entropy is often discernibly faster.
