windows 7 - how to get the locations of keyboard shortcut set for shortcut files

I have created keyboard shortcuts for many shortcut files.

Now I don't know for which shortcut file I have created a shortcut.
I want to know all the shortcut files for which I have created the shortcuts, so that I can delete some of them.
Is there a way by which I can know all the shortcut files for which keyboard shortcut has been set.
