Honestly I didn't try that, but with a quick glance I saw you are enumerating removable drives, that is not Everything is limited to. Further, did you think about the searches that everything can do? One simplest would be:

*.prg

and it handles many complex searches (just check the list in Help\Search syntax).

As a VFP app, I can't see a usefulness.

(Everything is one of those apps that is always in my taskbar in all the computers I use)

(and on Mac there is Spotlight search built-in + many apps doing same or similar thing - ie: easyFind)
