@igazor OK, I guess I don't need the batch file. I clear the cache files manually every time I quit the game, which I do even when I only want to switch between saves, and I have featured items disabled. I have not reset my active lot, because I hate having my active sims reset with MC. It changes too much with them. I suppose I could have them move to their second house, reset their home lot, then move them back. I will try that.
My main drive is an SSD, but "My Documents" and virtual memory are on a much larger secondary hard drive.
