I am using Lubuntu 11.10. When I call the context menu (right click) many programs appear to open some file.
For example, for
.tex files, besides TeXstudio and Leafpad, Gnumeric (what a strange option!) and text editor also appear.
So, I'd like to remove those bad options. For some extensions (
.txt for example) I could remove the wrong programs by deleting the
.desktop files somewhere in
How should I do this?
