Zemoxia25 The folder to move is the one in Documents. Is it an actual duplicate of the one in C:\Program Files or wherever you found the other? As in, do these contain the same data? If so, please let me know what data is there, not just "a Sims 4 folder" (for example) but what's inside.
What do you mean, you can't find Sims 4 in your graphics section? I'm not sure where you're looking or what you're trying to do here, so please let me know.
Please also let me know what antivirus you use, and whether OneDrive is running on your computer, even if you never use it.
