You put all the files in the top directory. Hint? It only holds so many files.
Fix? Make a sub directory and put things there.

I have a 1 GB USB 2.0 flash drive that returns a "the disk in the detination drive is full" message even though there's less than 450 MB of data on it. I'm only trying to add a 200 KB file.
I've tried to reformat and properties indicate that there should be 500 MB of available space on the drive.
Am I missing something?
