Different software packages use different file extensions, so if you can't open the R21 file, it could be because:

  • You don't have the associated software on your computer (Binary Data is the most popular software package that uses R21 file).

  • You may have Binary Data but your computer is not configured to associate R21 files with the relevant software.

  • The file is corrupt.
