✅ MS-DOS Subsystem Startup File

NT file is a MS-DOS Subsystem Startup File. When an MS-DOS-based application is started, Windows NT/2000/XP executes files specified in the application's program information file (PIF) or the Autoexec.nt and Config.nt files in the SystemrootSystem32 directory. Any changes made in one of these files take effect as soon as the file is saved and a new MS-DOS-based application is started that uses that file.

🔴 Can't open a .nt file?

When you double-click a file to open it, Windows examines the filename extension. If Windows recognizes the filename extension, it opens the file in the program that is associated with that filename extension. When Windows does not recognize a filename extension, you receive the following message:

Windows cannot open this file:


To open this file, Windows needs to know what program you want to use to open it...

If you don't know how to set the .nt file association, check the FAQ.

🔴 Can I change the extension of files?

Changing the filename extension of a file is not a good idea. When you change a file's extension, you change the way programs on your computer read the file. The problem is, changing the file extension does not change the file format.
