MDL files make use of different views to be seen and these views are flatshaded, textured, wireframe and smoothshaded. They are viewed with the use of the Half-Life Model Viewer. MDL files are also compiled with VTX files. These files are mostly used by Half Life, a first person shooter game wherein players play the role of Gordon Freeman, fighting their way out of a research facility that has gone wrong.

Half-Life Model Viewer and MilkShape 3D as well as other applications can also open MDL files.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .mdl. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
