The Optimized Storage features of your Mac help you save storage space by storing your content in iCloud and making it available on demand:

• When storage space is needed, files, photos, movies, email attachments, and other files that you seldom use are stored in iCloud automatically.
• Each file stays right where you last saved it, and downloads when you open it.
• Files that you’ve used recently remain on your Mac, along with optimized versions of your photos.

If you haven't yet upgraded to macOS Sierra or later, learn about other ways to free up storage space.

• The Storage pane of About This Mac is the best way to determine the amount of storage space available on your Mac. Disk Utility and other apps might show storage categories such as Not Mounted, VM, Recovery, Other Volumes, Other, Free, or Purgeable. Don't rely on these categories to understand how to free up storage space or how much storage space is available for your data.
• When you duplicate a file on an APFS-formatted volume, that file doesn't use additional storage space on the volume. Deleting a duplicate file 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.
