Record marked as obsolete and not updated for a long time.
The lmp file extension is associated with the Doom a 3D action first person shooter based on Id Tech 1 video gaming engine developed by id Software.
In Doom, Ultimate Doom and Doom II, it is possible to record a playing session; ie. you can save to a file exactly what you do during a chosen episode and level/map (these demo files have a .lmp suffix). This file can then be played back later so that you can sit back and watch exactly what you did. The file itself does NOT contain any graphics images.
The demo file merely records which keys get pressed and also the various mouse movements. However, there are certain key actions that are NOT recorded. These include using the ESC key to bring up the main menu and any actions taken using that menu. Also, you may find that using the mouse is not _quite_ as smooth as when playing normally - this is probably due to the overhead of having to record the various mouse movements as you play. One annoying thing is that the game _will_ record any use of the PAUSE key, so make sure you don't use it when recording a lmp file.
command line commands:
doom -devparm -warp (ep) (lv) -skill (num) -record (file)
The lmp files can be viewable in Doom computer game.
Probably cannot be converted to other formats.

The LMP format is used by Left 4 Dead to store data required by the game. It is a game resource rather than a document intended for direct use by the player.
An LMP file forms part of the game's installed files and works together with the other resources used by Left 4 Dead. The game manages these files internally while loading and running its content.
The format is specific to the Windows release of Left 4 Dead and is not a general-purpose interchange format.
Open an LMP file with the Microsoft Windows version of Left 4 Dead. The game reads the file from its installed game data, so it normally should not be opened by double-clicking it or edited manually.
If Windows does not associate the file with the game, start Left 4 Dead from its installed game client instead of selecting an unrelated application.
LMP files are proprietary game data and have no standard general-purpose conversion option. They should remain in the format expected by Left 4 Dead.
Renaming the extension does not convert the file.
