steam uninstallation

@imaniii1312  Your Steam and EA accounts own your game and DLC, not your computer.  So you can uninstall everything and it'll still be available in your game libraries when you're ready to reinstall.

As for how to free up more space on your computer, Sims 4 is the same size whether it's installed from Steam or the EA App.  Steam itself is small, as is the EA App itself, so you won't reclaim much space by installing either app alone.  But if you install Steam itself, that will also uninstall any Steam games you have because by default, all of these games are downloaded into a folder inside the Steam install.
