@CharmB789 If you move your 'The Sims 4' folder out of your Electronic arts folder, the game will created a new 'The Sims 4' folder when it re-starts, but the game saves and anything you have in your library, etc., will not be in the game when you re-enter it, as all of those things live in the 'tray' and 'saves' folders... and if you removed your old folder, the new 'tray and 'saves' folder will not include anything you have played thus far (as explained at this link: https://sims4.crinrict.com/eng/2014/09/user-files-explained/). If you moved your old, original 'The Sims 4' folder back in you may want to delete the localthumbcache.package file in your “The Sims 4” folder in case you are not seeing the correct thumbnails in your library, etc., then re-start the game so it updates these thumbnails to correct ones.
Please be very careful to keep a copy of your original 'The Sims 4" folder as your backup when doing any of this, as it should have your tray and saves folder with your original game saves (the games you played) and your tray folder (your library, etc.).
