File extension 003 description:
Third file (usually WinRar application file) of multi-volume archive.RAR is the native format of WinRAR archiver. Like other archives, RAR files are data containers, they store one or several files in the compressed form. After you downloaded RAR file from Internet, you need to unpack its contents in order to use it.
Some RAR files can be parts of multi-volume sequences. In WinRAR you can split a huge archive to a few smaller files, which are called volumes. They may have extensions .rar (the first volume), .r00, .r01, ..., or .part1.rar (the first volume), .part2.rar, ..., etc. If you need to unpack volumes, place all them to the same folder and start extraction from the first volume.
