Set up iCloud Drive on Apple Vision Pro
Use the Files app to store files and folders in iCloud Drive. You can access them from all your devices where you’re signed in with the same Apple Account. Any changes you make appear on all your devices set up with iCloud Drive.
iCloud Drive is built into the Files app on Apple Vision Pro, as well as devices with iOS 11 or iPadOS 13, or later. You can also use iCloud Drive on Mac computers (OS X 10.10 or later) and PCs (iCloud for Windows 7 or later). Storage limits depend on your iCloud storage plan.
