Open EXT File

The EXT extension files present, up to now, two different applications, namely:

Norton Commander Extension

In this application, the EXT format was a software extension used by Norton Commander for DOS / Windows 95.

In this case, the EXT format allowed users to modify files, such as changing file attributes and synchronizing directories, using a text-based interface.

For this use, the EXT extension is already considered unsupported and its use has been discontinued.

Generic Email Attachment

In this case, the EXT extension is a type of file that can be sent by a script or automated email program.

The EXT uses the generic file name, for example filename.ext, and can be a file created in one of many text or binary formats.

Normally the sending / receiving of an EXT file is transparent to the participants of the process, that is, the sender / receiver.

Therefore, if you receive an EXT file as an email attachment, it is generally not clear what the file format is.
