Items in context menu in Lubuntu

Question

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 .config subfolders.

How should I do this?

Answer 1

Simple, copy files like /usr/share/applications/XX.desktop, to ~/.local/share/applications,

And remove the unnecessary mimetypes, from the Mimetype= line

(You might need to re-login, not sure if LXDE reloades them automatically)
