What is a PAR2 file?
A .PAR2 file is a Parchive 2 File. The Parchive standard creates these files to hold parity data. People use this data to verify and repair corrupted or missing files in a set of downloaded files. Users often encounter .PAR2 files when they download large archives from Usenet or transfer data over unreliable networks. The format uses error correction algorithms to restore missing pieces of data.
How to open PAR2 files?
To repair files using a .PAR2 file, you need specialized software. Windows users often use QuickPar or MultiPar. Mac and Linux users can use the par2cmdline tool in the terminal. These programs read the .PAR2 file, check your downloaded files for errors, and fix them if you have enough recovery blocks. Because a .PAR2 file can have multiple meanings, we recommend using viewer.online/par2 to identify the actual format of your file.
