Nice to know that...
the Windows Search function works for something! It sure as hell isn't worth a flip to find files any more. When search reveals no files within the searched criteria, it may or may not be so. In my experience, I don't usually search for things of which I know their location.
Oh, and isn't it wonderful that you know the Windows keyboard combination to pull up that function? MS isn't happy about anyone else knowing it. Just as is the case with the file extension and its purpose. The list goes on and on.
