We have found M files on the Windows, Mac, and Linux operating systems. They are both mobile and desktop device friendly. The Popularity Rating for M files is "Low", which means these files are not ordinarily found on an everyday user's device.

M File Complications


Frequent M Opening Issues

Notepad++ Disappeared

Double-clicking your M file prompts the message "%%os%% Can't Open M File". When this happens, it is commonly due to Notepad++ missing in %%os%%. This will prevent you from double-clicking to open the M file because the OS doesn’t know how to handle it.


Tip: If you have another software that you know opens M files, you can select it by hitting the "Show Apps" button.


Outdated Notepad++

Occasionally, you might have an outdated version of Notepad++ installed that's incompatible with your MATLAB Source Code File type. If you do not have the proper version Notepad++ (or any of the other programs listed above), you may need to try downloading a different version of it, or one of the other software applications listed above. This issue mainly occurs when your MATLAB Source Code File file was created by a newer version of Notepad++ than you have on your PC.


Tip: You can sometimes get hints about the right program version by right-clicking on the M file, selecting "Properties", and looking at the version information.


Summary: Not having the right Notepad++ version on your computer can cause problems opening M files.


Associated Difficulties Loading M Files

Errors opening MATLAB Source Code File files can still occur even with the latest Notepad++ software installed on your computer. If you are continuing to have errors with loading M files, other external issues might be to blame. These other problems include (listed in order from most to least common):

  • Invalid M file references in the Windows Registry (the "phonebook" of the Windows Operating System)
  • Mistaken removal of the Windows registry M description
  • Invalid installation of a M-associated program (eg. Notepad++)
  • M file corruption
  • The M is infected with a virus
  • Device drivers for M-related hardware are out-of-date
  • Windows cannot load your MATLAB Source Code File file due to insufficient resources (eg. RAM)
