About the RAR file type:

If Windows cannot find the appropriate program associated with .RAR files, then your registry may have errors. Check your Windows registry for errors (includes file association errors).

.RAR is a data compression, storage and transfer file format. These files can be uncompressed using a range of available programs, using the proprietary RAR algorithm, however the most common windows package is WinRAR (shareware). An archive compressed using the RAR or WinRAR file compression programs might be divided into smaller files, which, in turn, might be labeled with the extensions .R00 through to .R99.
