The MDL format is a standard text-based format used by Simulink for saving simulation models. Each MDL file includes a list of elements, which each contain a list of values. The model data can be parsed by Simulink and displayed visually within the program.
Important: Until 2012, the MDL format was the standard model format used by Simulink. It has since been replaced by the newer .SLX format.
About MathWorks Simulink
MathWorks Simulink is a scientific application designed for performing simulation and creating model-based designs. It supports system-level design, automatic code generation, and continuous testing. The program includes a graphical editor, customizable block libraries, and "solvers," which can be used to model dynamic systems. Simulation results can be exported to MATLAB, MathWorks' technical computing application.

File Type 2
Half-Life Model File
Open manually; may be referenced by an application
★ ★ ★ ★ ☆ Common
Three-dimensional model used for characters and creatures in the Half-Life video game; created using polygons and texture mapping for detail; can be seen from different views (wireframe, flatshaded, smoothshaded, and textured) using the Half-Life Model Viewer.
Important: QC files are actually used by Valve's Source game engine, so they are not restricted to Half-Life models.
