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.
