dprssdblkhottie Your saves and other user content need to be in a folder called "The Sims 4" rather than in the SIMSIESS folder they're inside now. However, do NOT combine them with the Sims 4 folder in your first screenshot—that folder contains the game's program files, and having the two sets of files in the same location can lead to a variety of problems. So create a different folder on your external drive and place your Sims 4 user folder inside there.
