Before I replace one map for a new one, I rename the current map. For example, my current ModMap of MapX3Y1.jpg that has tiger striped sofa, chair and carpet, is about to be replaced with a new Mod Map. So I will rename it MapX3Y1Tiger.jpg and the new one will become MapX3Y1.jpg . All of the original maps that have been replaced by Mods have the ending 'Original' (MapX3Y1Original.jpg). Helps me keep my sanity since I have gone "Mod crazy"! LOL!

I also have a back-up copy of all of the original maps in a folder outside of the Virtual Families game folder.
