The Quick Way to Open Files with ASCII Extension

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

  • You don't have the associated software on your computer (Unknown Apple II File is the most popular software package that uses ASCII file).

  • You may have Unknown Apple II File but your computer is not configured to associate ASCII files with the relevant software.

  • The file is corrupt.

If You Don't Have Unknown Apple II File

In order to open your ASCII file, you will have to download Unknown Apple II File or another similar software package.

If Your Computer is Not Configured to Open ASCII Files

If you have the relevant software, but your computer still won't open the software, you will have to change the file associations on Windows or Mac. Depending on your operating system, you can ensure that your computer always open ASCII files using Unknown Apple II File or another program of your choice that uses ASCII files.

If that still doesn't work, you can get in touch with your software developer to find out what you can do. You can contact any of these developers for more information or assistance:

If the ASCII File is Corrupt


In some instances, you may receive an error message stating that the file is corrupt. If you have tried all of the above, and it still doesn't work, download or request a new copy to see if that works.
