Re: [ARCHIVED] How to use Mods/CC on PC
@BasiSK28 You're looking in the wrong location. The Mods folder is stored in Documents > Electronic Arts > The Sims 4; this is the user folder. The Sims 4 folder in your screenshot contains the game's program files, not the user data.
As a side note, I would strongly recommend uninstalling Sims 4 and reinstalling it to a location that's not inside Documents. OneDrive is currently syncing the program files, which in addition to unnecessarily taking up a lot of cloud storage (and possibly forcing you to pay extra for more storage), any hiccup with OneDrive could prevent you from updating or repairing the game, or even force you to reinstall at a later date.
The default install location of C:\Program Files\EA Games is fine, but so is almost any other location that's not inside Documents.
