The .s11 file extension is associated with Descent 2, a 3D first-person shooter developed by Parallax Software and published by Interplay for Microsoft MS-DOS and other platforms.
An .s11 file stores game data required by Descent 2. It is part of the game's internal data rather than a document intended for direct editing.
The file is used by the MS-DOS version of Descent 2 when the game loads its data.
Use the original Microsoft MS-DOS version of Descent 2 to open an .s11 file. Place the file in the game's expected directory and start the game; it normally reads the file automatically.
The file is not intended to be opened as a standalone document or edited manually.
An .s11 file contains internal Descent 2 game data, so it has no useful general-purpose conversion format. The original game uses the file in its existing form.
There is no standard export procedure for converting this file into a document, image, audio file, or other common format.
