- Desktop and Documents. Store all files from these two locations in iCloud Drive.

Files stored only in the cloud show a download icon , which you can double-click to download the original file. Learn more about this feature.
- Photos. Store all original, full-resolution photos and videos in iCloud Photos. When storage space is needed, only space-saving (optimized) versions of photos are kept on your Mac. To download the original photo or video, just open it.
- Messages. Store all messages and attachments in iCloud. When storage space is needed, only the messages and attachments you recently opened are kept on your Mac. Learn more about Messages in iCloud.

Learn more about prices in your region.
Optimize Storage
Click the Optimize button, then choose from these options.

- Don't automatically download attachments. Mail downloads an attachment only when you open the email or attachment, or save the attachment to your Mac.
Optimizing storage for movies, TV shows, and email attachments doesn't require iCloud storage space.
Empty Trash Automatically

Reduce Clutter

Some categories allow you delete files directly. (If you purchased the file from the Mac App Store, iBooks Store, or iTunes Store, you might be able to download it again.) Other categories show the total storage space used by the files in each app. You can then open the app and decide whether to delete files from within it.
Where to find the settings for each feature

Other ways that macOS helps automatically save space
macOS Sierra and later automatically takes these additional steps to save storage space:
- Detects duplicate downloads in Safari, keeping only the most recent version of the download
- Reminds you to delete used app installers
- Removes old fonts, languages, and dictionaries that aren't being used
- Clears caches, logs, and other unnecessary data when storage space is needed
How to free up storage space manually
Even without using the Optimized Storage features of Sierra or later, you can take other steps to make more storage space available:
- Delete files that you no longer need by moving them to the Trash, then emptying the Trash. The Downloads folder is good place to look for files that you might no longer need.
- Move files to an external drive.
- Compress files.
- Delete unneeded email: In the Mail app, choose Mailbox > Erase Junk Mail. If you no longer need the email in your Trash mailbox, choose Mailbox > Erase Deleted Items.

- When you duplicate a file on an APFS-formatted volume, that file doesn't use additional storage space on the volume. Deleting a duplicate frees up only the space required by any data you might have added to the duplicate. If you no longer need any copies of the file, you can recover all of the storage space by deleting both the duplicate and the original file.
- If you're using a pro app and Optimize Mac Storage, learn how to make sure that your projects are always on your Mac and able to access their files.
