Re: Downloaded sims onto a flash drive and now it's not working

@e0ef297wtck0  Your saves, mods, custom content, and any other user files all need to be within the Sims 4 user folder the game is reading.  Here's how to find it:

Once you have that file path, open exactly that location and place your user files inside.  If the game still doesn't read the files, please post screenshots of your saves and mods in their new location so I can take a look.
