DON'T defrag an USB flash drive :P
That's IDIOTIC and will BREAK the damn drive if you keep repeating it. Move stuff out, format it then copy back in a single step.
the files will be copied in sequence and therefore, defragmented.
If you run an defrag program not only it will take several hours to complete it will also waste a lot of write cycles on the flash drive, ruining the flash memory earlier than it's supposed to wear out.
