I’m using 8.0.1489, running under Win2k (on a very old machine).
It’s actually the root of G: which is where I have Windows and my program files installed, but I don’t suppose that should make a difference.
In any case, I moved the files over 6 hours ago and haven’t noticed any problems, so they’re about to be deleted. As for how they got on the root folder, I’m happy to leave that as a mystery.
