while i haven't used that application, i use The Unarchiver, it uncompresses a lot of file types, including tar and rar, but i don't think it does the other two you said, but it also does 7z
 
Thanks

Thanks Macmaniac, I didn't realise that I could obtain that sort of software from Apple.
 
Yep I would definitely advocate using The Unarchiver, it can handle about any archive you throw at it. There is also unRARX if you specifically need to do .rar files.
