.LMP File Extension

An LMP file is a game data file used by a video game developed with the Quake engine. It may contain graphics, music, sounds, sprites, demos, textures, or level maps. LMP files are often stored alongside other graphics files, such as .TGA, .PCX, or .XCF images, in a game's data folders.

LMP, or lump, files typically contain a single game asset, such as a 2D image. Quake and Doom .WAD files are comprised of several of these lumps, packaged into a single archive.

While most LMP files contain 2D images, some contain other types of game data. For this reason, Quake and Doom modding programs that can open some LMP files may not be able to open others.

LMP files are not meant to be opened. However, some Quake and Doom modding programs, such as AdQuedit (Windows) and XDRE (Windows), can open some types of LMP files.
