Re: I moved my documents folder from the C: to the D: and now my game restarted

My sims 4 game installed the game files in the following location (after moving my Documents -folder):

C:\users\username\Personal\Electronic Arts

If you want to retrieve data from your old games, copy the contents of the saves-folder (Electronic Arts\The Sims 4\saves) from the old location to the save folder of the new location. 

Do the same for the contents of the tray-folder (copy them into the tray-folder)

The old location is most probably: C:\users\username\Documents\Electronic Arts

If you want to move the location of the Personal -file, edit the following registry in registry editor:

Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Personal

Change the value of Personal to e.g. D:\Personal, or whichever location you want the Sims 4 game files to be saved into. 

I chose mine to save to D:\Documents, for example. 

After you move any folder location, remember to copy the contents of the old location. 

After copying the data, you can remove the old folder.
