Nothing, NOTHING can be worse than Windows! I'm sorry to hear about your crash, man... That really sucks. If there's any way I can help out... I'm not sure how Bryce would be related to your models folder crashing, or did you mean the models IN your Bryce libraries? Backing things up is always a safe option... Bryce 5 and 4 also had a similar bug, where if you put too much stuff in a library folder, it would smoke the whole folder sometimes. Not pretty. Nobody ever figured out how much "too much" was, exactly, either. Best to just zipfile it once a month or so...
