Store files in iCloud Drive on Mac
With iCloud Drive, you can safely store all kinds of documents in iCloud, and access them from any of your devices and on the web at iCloud.com.
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 devices and they must meet minimum system requirements.
Note: 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.
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.

Store your Desktop and Documents folders in iCloud Drive
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 devices and iCloud.com.
On your Mac, choose Apple menu
Click iCloud on the right, click iCloud Drive, then make sure iCloud Drive is turned on.
Turn on Desktop & Documents Folders.
If this option isn’t shown, click Options, then select Desktop & Documents Folders.
Click Done.
After you turn on Desktop & Documents Folders, your Desktop and Documents folders are moved into iCloud Drive. They also appear in the iCloud section of the Finder sidebar on your Mac, and in the Files app on your iPhone or iPad. See the Apple Support article Find files on your iPhone or iPad in the Files app.
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, 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.
