PAR Buddy!

MultiPar does archival-grade file verification and repair to protect files from all forms of loss or corruption. Backups alone are not enough because data will gradually "rot" without MultiPar. Data loss can be caused by errors in backup copying, deletion, software bugs, hardware errors, viruses, tampering, etc. MultiPar can restore data even if some files are completely erased.

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.

MacPAR deLuxe is a utility program that runs on the Apple Macintosh. It is useful to you if you download (or upload) binary files from internet newsgroups (a.k.a. “Usenet”).
