File Extension RAR
Definition
In computing, RAR is a proprietary file format for data compression and archiving, developed by Eugene Roshal (hence the name RAR: Roshal ARchive). The filename extension used by RAR is .rar. If a RAR-archive is broken into many smaller files (a multi-volume archive), as is often the case when it was distributed on Usenet, then those smaller files carry the extensions .rar, .r00, .r01, .r02 etc. and most unrar programs reconstruct the whole archive when provided with the .rar file.
Windows Cannot Open RAR Files?
If Windows cannot open RAR files you may not have the appropriate program installed or have a registry related error. We strongly recommend you run a free registry scan.

Windows Registry is a critical component of your Windows operating system that governs
the operation of Windows. Without a clean and well-organized registry, your Windows system is vulnerable to corruption,
freezing, and crashing.

Computers perform best when they receive regular, professional maintenance. The installation and un-installation of software, hardware, and drivers often leave remnants behind in your registry, resulting in a tangle of unused applications, broken drivers, and incomplete and empty command signals. This mass of confusion slows down your computer and if not addressed promptly can lead to serious problems such as computer not recognizing file extensions, freezing, programs not responding, and system crashes.
