Re: Want to uninstall everything besides my households

@kaylajoan  The Sims 4 folder in Documents > Electronic Arts stores user data: saves, mods, households, etc.  Saves are in the saves folder, and saved households and builds (what you see in the in-game Library) are in Tray.  So you could set aside the Tray folder, and the saves folder if you're actually saying you want your saves preserved, and then delete the rest of this Sims 4 folder.  Start the game once to generate a new folder, then move the contents of Tray and possibly saves to the new folder.
