My understanding is that he has two arrays: the first containing 50,000+ pathnames, and the second containing 10,000 strings which may match a filename in one of the pathnames. I don't see how you exclude those matches with a regex, unless you concat all 10,000+ strings together with pipe symbols, and I doubt a regex like that would be very efficient.
