I have more to add :
The Sims 3 Cleaner by Delphy
This program is good to scan your files. Especially when you are looking for a bad one like those nasty boots and Doll.
Also by Dephy :
The Sims 3 Dashboard
This program is just like the one we used for TS2. it scans all of your CC files. Shows duplicates , TS2 files
that may have been installed and corrupted files. This program also deletes your caches .
Sims 3 Log Crash Analyzer
This program does exactly what it says lol. It will tell you why your game crashes with helpful links to fix the crashing.
I hope this is helpful to you all .
