Please, for the love of God, separate the different character's save files. It makes absolutely no sense to just leave all the saves jumbled up like that. I just lost my level 30 Nord because of this. I had put over 30 hours into him already and now it's all erased in the blink of an eye. I am totally discouraged over this and at the same time pissed off over how this could have been avoided by implementing a simple feature that should have been obvious. Yes, I know that technically it's my fault. I don't dispute that. But when you play one save file, you get in a habit and start saving on autopilot over the nearest game that isn't "autosave" and it could have been prevented so easily.
This is something that I have serious envy regarding the PC. Users can fix things like this extremely quickly...
