Good Evening Everyone, ok since I just installed Mods today for the first time for Sims 3, I am cleaning out my Origin files like I do multiple times a day, especially if I start lagging and there are 2 new folders there CustomBoxartCache and Download Cache is it safe for me to remove them or are they like my LocalContent Folder and not to be touched?

Thanks in advance for the help *smile*
 

CustomBoxartCache keeps track of your settings and shortcuts in the Origin Client the Download Cache is temporary spot that Origin uses when you download games and Origin Client updates and clears itself once the game or update is installed.
They can be deleted but I'd probably leave the CustomBoxartCache alone the other one doesn't really do anything until Origin calls on it but you can probably leave it as well.
