Thanks for such the quick response. I think I understand what you're saying. My thought process was it's possible for my local storage and iCloud to be two separate entities, when in fact--it can never be that, not fully anyway. I was trying to use iCloud as an external storage and pull out Sims 4 game files when needed. I now understand iCloud is a sync solution, not a storage solution.
To just make things simple, I'm going to take your advice with the 128GB thumb drive. Last thing-- I don't ever have to worry about "losing" the game/application with a thumb drive right? If something happens with the thumb drive, I can always go back through Origin, right, and re-download? Still trying to understand the concept.
