Handle with care.
The Unarchiver is a new utility that will uncompress many different formats so you don’t have to download each uncompression apps separately such as Stuffit, UnrarX, etc.
It works in the same way as Mac OS X’s default app BOMArchiver does. You can set a preference to use this utility instead of BOMArchiver for uncompression.
