What is an MDL file?

An MDL file is a model file used by Warcraft III, a real-time strategy game developed by Blizzard Entertainment. It stores a 3D model, including objects, meshes, and textures for buildings and units. MDL files allow text-based editing of model properties before generating a binary .MDX file used by Warcraft III.

More Information

MDL files use a nested structure to create model properties. For example, a material element may include a layer property which in turn defines a transparent property for the layer.

NOTE: MDL files are the text version of MDX 3D model binary files. They can be converted to the MDX format using the MDLX Converter program. From there, you can use several modeling tools to edit the model.
