Re: “How do I install Sims 3 on a SD card?”

@tyler2022144  Create a folder on the SD card, called whatever you want (but not "The Sims 3").  Open the EA App, click Sims 3, then Install, and choose the folder you created as the destination.  The App should take care of the rest.  You will of course need to uninstall the game first if it's currently installed.

Having said that, performance will be significantly worse when Sims 3 is installed on an SD card than if it were on an internal drive.  SD cards aren't as fast as other common types of storage.
