Then you can just dump all the package files into your mods folder.
It takes about five seconds to point it to a folder of sims3packs and convert them all. You can convert Sims3Packs to package files using a program called 'Sims3Pack Multi Installer' by Delphy. If you want to streamline the CC installation/sorting process, I recommend using.
What exactly do you mean by 'clean out'? Are you looking to sort through them and delete the ones you don't want? Find bad CC? Just find out what's in each file?
