It looks like the sims4, like many other games saves your user files in your user profile directory. So you cannot move the folder without changing where windows will store your user files: https://answers.ea.com/t5/Origin-Client-Web-Technical/Can-I-change-the-directory-for-the-save-files-of-games/td-p/4027118
You can change that in your windows settings but when I did that on my previous computer I thought it was too confusing where my files ended up.
If you want to move where the game itself is located, then you just need to reinstall it through origin.
