Sorry to be a pain, and possibly ask another daft question.

I currently have a 4Gb USB memory stick which I've installed several games on, plus it has several SNES roms. As its getting a bit full I've ordered a 32GB stick to use instead. Is there an easy way to copy everything from the 4Gb to the 32Gb using a Windows PC?

When I look at the memory stick in Windows I can't see the files for the games and they don't show if I change it to show hidden.
