Par-N-Rar is a graphical utility which accepts a directory as input
and will repair/verify any PAR/PAR2/SFV/MD5 files in that directory.
Once it verifies a set of files, it will attempt to unRAR them. Once it
finishes unRARing a RAR archive, it will (optionally) remove the
original PAR/RAR files.
For more details about using Par-N-Rar, run the setup and view the help file.
For more information on PAR and PAR2 files, see the parchive project.
For more information on RAR files, see WinRAR.
