LucasArts game resource file
File type: Game file
An LFD file is a game resource archive used by LucasArts computer games, including Star Wars: Dark Forces.
It belongs to the MS-DOS version of the game and is normally used by the game rather than opened separately.

The LFD format was used by LucasArts to package resources required by older computer games. In Star Wars: Dark Forces, these files are part of the game's installed resource data.
An LFD file may contain data used for the game's presentation and operation, rather than user-created documents. The game loads the resources from its installation files while running.
An LFD file should normally be left in the Star Wars: Dark Forces installation directory, where the MS-DOS game can access it. It is not intended to be opened as a standalone document.
To use the file on a modern computer, run the original MS-DOS game in a suitable DOS environment or emulator. Opening the file directly may only display archive or resource data and will not reproduce the game content.
LFD files are game resource archives, so they do not have a useful general-purpose conversion. The game can use them in their original form.
Specialized extraction or editing tools may be able to access individual resources, but extracting them does not produce a converted replacement for the original LFD file.
