@Momoll:Those
.package file are copies of the content of the
.sims3pack installed through the Launcher. It's only copies (hence the "backup" in the folder name I guess), so they can be safely deleted.
It's the DCCache folder that contains the files of installed content read by the game (in
.ebc and .
dbc formats). Those are the ones to keep.
Basically, you can see a
.Sims3pack as some kind of
.rar or
.zip. It's a container for other files. The Launcher opens them, extracts the content and places it in the appropriate folders, plus a copy as
.package in the DCBackup when needed.
I don't have many things installed in my own folder right now, but from what I see, Sims3packs install themselves as:
- Build & Buy mode & CAS items (from the Store for instance) go in DCCache as .ebc or .dbc (+ copy as [weirdname].package in DCBackup)
- Worlds (Riverview, Barnacle Bay or player made) go into InstalledWorlds folder as .world (+ copy as [worldname]_objects.package and [worldname]_sims.package in WorldCaches folder)
@VampirePlasma: look for a WorldCaches folder and not file. You can delete the files inside this folder
[Edit: Only if you play on Windows]. The next time you load a save or create a new game in one of the downloaded worlds, the loading time will be a bit longer because the game is recreating those files you deleted.
Edit: Mac Users, do not delete the World Caches files, you must keep them.
