The Unarchiver is a free archive decompression tool. It is currently my "unpackager" of choice because it is incredibly easy to use and it seems to support every format out there.
I have The Unarchiver configured so that it deletes the original package or archive after decompression and so it extracts the compressed file or files in the same folder were the archive was. This saves a lot of time for me, and I can always go to the Trash and recover the archive if I want to restore it.
The Unarchiver is as fast as any other decompression tool out there. 350-megabyte files decompress in under 10 seconds on my MacBook Pro. It has never crashed for me and there have been only a few instances in which it couldn't handle a file.
Pros
- It works very well
- Good format support
- Easy to use
Cons
- None
A really good application to have.
