What are RAR files?
RAR files are a type of file compression, similar to the more commonly known .zip files.
RAR stands for Roshal ARchive. It is a proprietary archive file format that supports data compression , error recover, and file spinning. After you have downloaded a RAR file from the Internet, you need to unpack its contents in order to use it.
The file name extension used by RAR is .rar for the data volume set and .rev for the recovery volume set. 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 of them into the same folder and start extraction from the first volume.
What supports RAR files?
Third-party programs that can read (unpack) RAR files include: WinRAR (Windows), WinZip (Windows), 7-Zip (multiplatform), Bandizip (Windows, Mac OS X), UnRarX (Mac OS X) and StuffIt Expander (Mac OS X).
All RAR file downloads from the Time + Space website are downloaded and expanded through the Connect Application which is sent to you via email after purchase. This is designed to remove your need to search for a RAR file expander.
