The Quick Way to Open Files with CAT Extension

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

  • You don't have the associated software on your computer (Unknown Apple II File, UNIX Configuration File, and Casio Calculator Program are the most popular software packages that use CAT file).

  • You may have Unknown Apple II File, UNIX Configuration File, or Casio Calculator Program but your computer is not configured to associate CAT files with the relevant software.

  • The file is corrupt.
