Hi there, I have a pretty big DropBox folder (80GB) I want to move over to iCloud so that I can use iCloud as my backup drive and so that I can manage the files on my Mac without having them on my computer natively. How do I move the photos and videos from DropBox to iCloud? I want to save all the photos I take with my phone to my iCloud folder but I don't want them to save on my actual phone itself. How do I set this up? Thank you in advance!
