Adding context menu in konqueror

Hi All…i was trying to add new actions in context menu in konqueror. I don’t know which is the exact directory where I need to create the .desktop files. I tried some default directories like /usr/share/apps/konqueror/servicemenus/,
~/.kde/share/apps/konqueror/servicemenus/ etc. But it didn’t work. Can you plz help?

I am using opensue 11.1 with kde 4.2.3
