The Worlds of Rflong7 =D

Rflong I did not go into the saves folder, I went into the downloads folder as you told me. It contains everything I have ever downloaded from worlds to hair styles, and I made copies of worlds that I wanted there or at least I think they are copies when I moved the copy to the desktop it said shortcut. In the downloads folder there green plumbbobs next to each name of the item. I have saved games from the save file to the desk top, but what I am hoping to do is to save the worlds themselves, in case I ever have to reinstall the sims games for whatever reason, the worlds I want are no longer available. So is that what I did. and can you delete items from the downloads folder?
