QuickPar is a computer program that creates parchives used as verification and recovery information for a file or group of files, and uses the recovery information, if available, to attempt to reconstruct the originals from the damaged files and the PAR volumes.

Designed for the Microsoft Windows operating system, it is often used to recover damaged or missing files that have been downloaded through Usenet.[3] QuickPar may also be used under Linux via Wine.[4]

Par2 file creation screen

There are two main versions of PAR files: PAR and PAR2. The PAR2 file format lifts many of its previous restrictions.[5] QuickPar is freeware but not open-source. It uses the Reed-Solomon error correction algorithm internally to create the error correcting information.[6]


Though QuickPar works well, it is currently considered abandonware, since there have been no updates for it in 14 years. The software, MultiPar, is actively being developed by another author named Yutaka Sawada, who is adding support for the new PAR3 file format.
