File Extension M

File type: Mathematica Input File

About the M file type:

If Windows cannot find the appropriate program associated with .M files, then your registry may have errors. Check your Windows registry for errors (includes file association errors).

The .M file extension identifies Mathematica Input files (developed by Wolfram research), which may contain instructions for this mathematical application. To execute .M files fully you will need to install Mathematica. However the files can be edited using a simple text editor.

Additional Information:
The .M file extension also identifies Objective-C implementation files. Other programs and formats known to use the .M file type include Matlab function files and Limbo interface declaration files.
