What are REV files, and how do I use them?
They are Reed-Solomon parity files (like PAR files) created by WinRAR V3.0 or later. The REV stands for “REcovery Volume”. WinRAR uses them to repair damaged archives, including the replacement of missing RARs. They are created by WinRAR at the time of the creation of the RARs if that option is selected by the creator of the archive. For full utility you need WinRAR 3.1 or later to create and use REV files.
