There is only one file type that uses the .L3D extension:
Black & White Graphics File
Graphics file used by Black & White, a game where players try to control villages acting as gods; may contain models, textures, and other images; used to store game icons, creature model meshes, weather system models, and other game graphics.
L3D files are located within several directories of a Black and White installation, including the \Data\CreatureMesh\, \Data\WeatherSystem\, \Data\Citadel\Icons\, and \Data\Misc\ directories.
L3D files are also used by the Creature Isle expansion pack to Black & White.
