The Quick Way to Open Files with CMD Extension

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

  • You don't have the associated software on your computer (Unknown Apple II File, Summit Contact Manager Contact Database, and Command File for Windows NT are the most popular software packages that use CMD file).

  • You may have Unknown Apple II File, Summit Contact Manager Contact Database, or Command File for Windows NT but your computer is not configured to associate CMD files with the relevant software.

  • The file is corrupt.

If Your Computer is Not Configured to Open CMD Files
