Do you have the Mods\Packages framework set up to work with package based files like package-based CC and mods? If not, I'm afraid I'm not really seeing the point of doing this to the poor sims3packs. They need to be installed through the Launcher.

If you already have this, then it sounds like you require a package file editor like S3PE to examine each individual package file for clues as to what it's for.
