Heya,
There's no easy way to do that, you'll have to open your flash manually and delete duplicates. You can use Total Commander if you feel it's easier to manage and select multiple items. Or you can also make batch file in Command Prompt, using widgets you can delete everything with "COPY" in file name ;)

There are programs that can find and help you delete duplicate files, movies and pictures the CCleaner has this feature Duplicate Files Finder is another solid, if simplistic option.
