Use iCloud Drive to store documents on your Mac, iPhone, and iPad
With iCloud Drive, you can safely store all kinds of documents in iCloud, and access them from all your computers, iOS devices, and iPadOS devices. If you like, you can have all the files in your Desktop and Documents folders stored automatically in iCloud Drive. That way, you can save files right where you usually keep them, and they become available on all your computers, iOS devices, and iPadOS devices.
You can use iCloud Drive on Mac computers (OS X 10.10 or later), iOS devices (iOS 8 or later), iPadOS devices, and Windows computers with iCloud for Windows (Windows 7 or later required). You must be signed in with the same Apple ID on all your computers and devices.
You can also use iCloud Drive on the web at iCloud.com.
To set up iCloud Drive on the web, an iOS device, an iPadOS device, or a Windows computer, see Set up iCloud Drive on all your devices in the iCloud User Guide.
Set up iCloud Drive
If you haven’t yet set up iCloud Drive on this Mac, you can do it now in iCloud settings.
On your Mac, choose Apple menu
Click iCloud on the right, click iCloud Drive, then click Turn On.
Click Done.
Important: After you turn on iCloud Drive, the documents you’ve stored in iCloud Drive are only available on your computers, iOS devices, and iPadOS devices that meet minimum system requirements and have iCloud Drive turned on. Your documents in iCloud Drive are also available on iCloud.com.
If you have devices with iCloud Drive turned off, documents and data on those devices aren’t kept up to date with documents and data on your devices with iCloud Drive turned on.
Store your Desktop and Documents folders in iCloud Drive
On your Mac, choose Apple menu
Click iCloud on the right, click iCloud Drive, then click Options.
If you don’t see Options, make sure iCloud Drive is turned on.
Select Desktop & Documents Folders.
Click Done.
After you select Desktop & Documents Folders, your Desktop and Documents folders are moved into iCloud Drive. They also appear in the iCloud section of the Finder sidebar.
Tip: You can quickly view the sync status of iCloud Drive on your Mac. Move the pointer over iCloud Drive in the Finder sidebar, then click the status or information icon.
If you can’t move or save a document to iCloud Drive
If you can’t move or save a document to iCloud Drive, your iCloud storage space may be full. The document stays on your Mac, and is uploaded to iCloud Drive when space becomes available.
iCloud Drive shares your iCloud storage with iCloud Photos, iOS and iPadOS device backups, messages and attachments in iCloud Mail (your @icloud.com email account), and more.
To get more space, do the following:
Upgrade your storage. See Manage iCloud storage.
Remove items you don’t need to store in iCloud Drive.
