Re: transfer sims 4 to hard drive, tips?

@yesimjill  You can move the game's program files to a second drive through Origin's Move Game feature, although loading times will be faster if the game is on a solid state drive.  But the Sims 4 user data folder will still be in Documents\Electronic Arts, and if you move that folder, the game won't be able to find it and will create a new one with no content.

The easiest way to move the user data folder is to move all of Documents to your secondary drive.  This is simple and supported by Windows:
