What do you make of these file\folder names?

My friend found this on his flash drive. Norton shows no viruses or anything, but none of the directories or files can be opened. If you recognize the file path at the top of the window please let me know what it is from, but I think it is some sort of data corruption. That folder apparently takes up 64.1 gigabytes of space as well! The flash drive is only a 4 gig and shows 500mb of free space. what is going on with this?
