What is a WM file?

WM files mostly belong to Windows Media Player. A WM file is not a single format but a label used for different file types.
One common format is a compressed video container that uses the RIFF structure. This file holds audio and video data for streaming and playback in Microsoft’s ecosystem. It is meant to work with applications like Windows Media Player. For more details, you can visit Microsoft Windows.
Another use of the WM extension is for a simulation file in the Working Model 2D software. These files store model data used for simulations. More info is available at Working Model 2D.
There is also a variant used as a project file for Windows Movie Maker. In this case, the file records editing details like clips, transitions, and timeline settings.
Key formats include:

Compressed Video Container: Holds multimedia data using RIFF.

Simulation File: Used by Working Model 2D for dynamic model data.

Movie Maker Project File: Contains video editing information.
