I installed mathematica 7.0 and it registered itself to open all *.m files and changed their icons to the mathematica logo.

The problem is most of my *.m files are MATLAB source code.

I've figured out how to get all the files to open with gedit by default, but how do you change all of their icons back?

By the way, all the *.m files show as MIME type "application/mathematica" whereas they used to show as "text/plain."


Any help would be appreciated!
