@Jude525: I've found that it's a good idea to make a copy elsewhere (on a second drive, if you've got one) of a clean install of Sims 3; that is, an install of Sims 3 before you add any store items or CC to it, but have all of your EPs and SPs installed. Then do another backup copy of Sims 3 after installing all your store items, but before installing any CC. Then put a text file in each of those Sims 3 folders stating what that install of the Sims 3 is for, so you know which one you need to re-copy back if your regular Sims 3 install gets corrupted.
Doing this can save you an awful lot of time and hassle later, and it doesn't really take that much time to copy them over. Well, maybe it does, but it takes less time than doing a complete reinstall. :) I usually start the copy process, then go to dinner or something. And as I said, copying them to another (either internal or external) hard drive is a good idea, in case it's your hard drive itself that decide to crash and burn.
Backing up your saves onto that drive goes without saying. I personally have a 4TB drive I use solely for my Sims 3 backups; if my main hard drive does a crash and burn, or if a game save gets corrupted, the most I will ever lose is a day of gaming/building. Of course, if the backup drive does a crash and burn, I'm lost...
I used to work for a software backup company. It shows. :)
Edit: Oh, I forgot the whole reason I came here in the first place - to comment on your lots! Duh! :sweat: I really like your work, although I think my absolute favorite is the wedding venue. I wouldn't have thought to use those roof pieces for something like this, but it's really lovely.
