When swapping between bootcamp and mac, my files all go elsewhere
So, I've recently gotten bootcamp on my Macbook pro 2016. Everything works really well, except that whenever I swap to mac again, all my files go to the boot camp drive. This makes it really weird because I downloaded Rainbow 6 siege the game, but the computer states that I do not have it downloaded, but if I try to drag it to the proper folder, it just states that there are folders open that don't allow it to occur. How can I fix this, and how can I make it so that all my files remain in place?
