Opening EXT files

Did your computer fail to open an EXT file? We explain what EXT files are and recommend software that we know can open or convert your EXT files.

What is an EXT file?

Files that contain the .ext file extension are most commonly associated with the Norton Commander software application. This application is primarily used on the DOS and Windows 95 operating systems.

Norton Commander allows a user to modify the files on their hard drive using a text-based interface. The files that are modified using the Norton Commander program are saved using the .ext file suffix.

The .ext file extension is also used for email text attachments by a variety of POP 3 email applications. When a user sends or receives an attachment using the email program, the attachment is saved using the .ext file suffix. This allows the user access to the file attachment without online connectivity.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
