Unfortunately, I didn't back up the objects.... Only about half a dozen were models that I had made in Bryce, with the majority being things I'd DLed over the past year and intended to use. This file system is going to take some getting used to, but I guess I can at least make copies of the other preset catagories before I reinstall (so that I don't lose all the wonderful textures and other models that I've added). They can just replace the ones that Bryce will put there, right?
