Copying file to folder (parameter incorrect)

I am trying to move the songs from my ipod to a computer and all i need to do is copy the folders to my hard drive, but everytime i send it to the folder it says "Cannot copy GTPQ: The parameter is incorrect." What is the easiest way to resolve this problem?

Download and install TeraCopy.
Then try it again. Helps a lot for problem copies

Are you using iTune to copy/transfer?

If so, I guess that will done in synchronizing your ipod and PC folders.
