Cris B - if GD changes the folder and file names in any way then I suggest you don't use it. The problem arises when you want to use the GD copy, either to restore to a local HDD or via a content server.
I assume you're familiar with this thread ==>>
WARNING - Google Drive Incompatible with Calibre!, and the threads it references. They may give some clues about when GD corrupts the folder names.
Before I would use it, I'd want to see something official from Google that admitted they did change folder names, and that they have ceased doing so from such-and-such date.
