how to delete duplicates

[fenpeppertree]

I have 511 sets of identical duplicates in a scrap container. How do I delete just the first or second file in each set? Each set contains exactly two files with identical information. All are on the same drive, but not necessarily in the same folder. Just want to get rid of one or the other in each set.
