When I use flash drives, I just drag and drop files to them. None of the burning and making sure you have the right kind of disc etc. That is a bit strange that you can "see" the disc on Windows 7 and what's on it, but not Windows 10.

I could see it in Windows 10, and once you reminded me where to look, I could see that there was no available space on it. I just don't know why there's no space on it though.

So, question which I think I may have missed... could you "see" the game file on it on both systems?

Yes.

Thanks! Sometimes I forget what I asked and what I didn't. So, the disk has become full, but can't be reformatted. I have no other suggestions, sorry!

No problem!
