.DN1 File

The dn1 file extension was in the past used for the game data files in Duke Nukem 1 episode 1 "Shrapnel City", an action platform computer game for MS-DOS, developed by Apogee.

This dn1 file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.

Files with dn1 file extension might be found as part of old Duke Nukem: Shrapnel City MS-DOS computer game.
