Not that I'm aware of.

Sure, but I'm not sure how accurate creation time is on Windoze. You'll
need to stat each file and sort on the saved time. Modification time is
usually a better bet if it suits your needs. You could save the name as
the key and the ctime as the value in a hash and then sort the hash by
value (to keep the two sync'd together).
