Coming from the Windows world most of us people know the .rar archive format very well. Besides the newer 7zip format, Rar allows a good compression and is widely used on internet distribution.
II. What do we need?
People who only need to have a decompressor for compatibility reasons can use MacPar Deluxe. Users who also want to be able to compress files aswell need to get SimplyRar:
» For Uncompressing only use MacPar Deluxe (download here)…
» For Compressing and Uncompressing use SimplyRar (download here)…
III. How do these tools work?
MacPar Deluxe is intended for unpacking only. The part of the name Par indicates its main use, as it is a tool for people downloading things from the usenet. Par files are files that contain repair information for damaged main files. Anyway: MacPar Deluxe also contains a very simply unrar engine.
SimplyRar is a graphical user interface for the free command line version of rar for Mac OS. It contains (almost) all features of the command line. As a switcher I currently cannot tell what features are missing in comparison to WinRar for Windows.
