EXTファイルとは？
An EXT file is a configuration file used by Norton Commander, a discontinued file management program. It stores plain-text definitions of file extension associations and custom commands that Norton Commander can perform on specific file types. The commands allow the program to run external tools or scripts when a user selects or opens a file within the Norton Commander interface.
詳細情報
The rules contained in EXT files describe how Norton Commander should handle different file extensions. Each rule typically specifies a file type and the command that should run when a user performs an action, such as viewing, editing, or executing the file.
For example, an EXT file might instruct Norton Commander to launch a text viewer for .TXT files or run a decompression tool for archive files. This system allowed users to extend the functionality of the file manager without modifying the program itself.
注: Norton Commander was originally developed for DOS and later adapted for early Windows systems in the 1980s and 1990s. Norton Commander has been replaced by modern file managers, making the EXT format obscure.
EXTファイルの開き方
You can open an EXT file with any plain text editor, such as Microsoft Notepad or Apple TextEdit. However, the file only functions as intended when used within Norton Commander, which is discontinued.

File that may be sent by an automated emailing script or program; uses the generic filename filename.ext (the file's name and "ext" for "extension"); may be a file created in one of many text or binary formats.
詳細情報
If you receive an EXT file as an email attachment, it is generally not clear what the file format is. Therefore, it is best to contact the sender of the email to determine the file format.
Many automated emailer code examples available on the Web use the generic string "filename.ext" when referring to the email attachment. Therefore, it's possible the script author did not replace the filename string with the appropriate attachment filename when sending the email.
