.r00 File Extension ? A Detailed Description

The .r00 extension is primarily used with file archives compressed using the RAR or WinRAR file compression utilities. RAR is an archive file format that supports data compression and was originally developed by Eugene Roshal and is currently licensed by Win.RAR GmbH.

An .r00 file is WinRAR or RAR compressed archive that could be a single archive or one of the many parts of a split archive.

So what is a split archive? When the size of the compressed archive is huge and cannot fit into a storage device, the archive is broken into various volumes. In such a case, you are likely to find that file extensions are numbered as .r00, .r01, .r02?. .r97, .r98, .r99. To understand this better lets see the example illustrated below:

If you create a RAR archive with 8 parts named bigarchive; the archive will have the following components:

  • bigarchive.rar ? File extension RAR
  • bigarchive.r00 ? File extension R00
  • bigarchive.r01 ? File extension R01
  • bigarchive.r02 ? File extension R02
  • bigarchive.r03 ? File extension R03
  • bigarchive.04 ? File extension R04
  • bigarchive.05 ? File extension R05
  • bigarchive.06 ? File extension R06
  • bigarchive.07 ? File extension R07

Files with the .r00 file extension are compressed files and their Mime type is application/x-rar-compressed.
