Re: Sims 3: Delete piggybacked package files?
@hunnypooh1 There are two different folders you need to address. DCBackup is the one with ccmerged.package in it. Deleting the other files won't uninstall the cc, although bad cc can sometimes "reinfect" a game from here. To remove a cc item from your game, you have to either uninstall it from its corresponding .dbc bundle in DCCache, via the launcher, or delete the .dbc bundle entirely. That was the process I was describing.
If you're converting your Sims3Pack files to .package files (is this what you're doing?), you can just add and remove the files until you see that the skin isn't in-game. Or you could keep the sim and get rid of all the other cc. The point of the unpacking process is to make cc easier to add and remove, instead of having to go through the launcher. But it's one or the other—either install a pack directly, or convert it into .package files and add the cc to Mods\Packages.
Also, some sims still look like they have cc until you take them into CAS for the first time. I don't know which items are affected this way—it applies to sliders, for example, but probably not clothing.
Anyway, please be more specific in describing the process you've used so far. Where to go from here depends on your approach. Also, if you'd prefer to start from scratch with your cc without losing your save data or other content, I can walk you through that too.
