>That said, if what you're trying to do is clean out debris, you could create a new project, add the main program and then Build project to pull in everything that is referenced. It's then easy to write code to compare the two projects and see what's not there. In fact, I have some code along these lines in the July FPA.

The only missing files would be images or text files referenced in code or in property values when you rebuild the project and only include the main program.
