Running out of disk space on your Mac? If you use iCloud Drive, macOS can quietly move rarely used files to the cloud and keep only lightweight placeholders on your drive — and you can force it to happen right now for your biggest space hogs. Here’s how to offload files to iCloud on your Mac and reclaim gigabytes in minutes.
How iCloud storage optimization works on Mac
When Optimize Mac Storage is switched on, macOS automatically removes the local copies of files you haven’t opened in a while, as long as they’re safely stored in iCloud Drive. The files still appear in Finder with a small cloud badge — double-click one and it downloads again instantly. Nothing is ever deleted; it’s just parked in the cloud until you need it. Apple’s guide to freeing up storage space on Mac explains the official options in more detail.
How to enable Optimize Mac Storage
First, make sure automatic optimization is switched on:
- On your Mac, open System Settings.
- Click your Apple Account at the top of the sidebar.
- Open the iCloud Drive settings.
- Turn on Optimize Mac Storage.
From here on, macOS will offload files on its own whenever space gets tight. But if you need room right now, you don’t have to wait.
How to force-offload files to iCloud manually
To push specific files or folders to the cloud immediately:
- Open Finder and navigate to a synced folder — anything inside iCloud Drive works.
- Find a large file or folder you don’t need locally right now. To spot the biggest ones, check System Settings > General > Storage first.
- Right-click (or Control-click) the file or folder.
- Choose Remove Download from the menu.
The local copy is removed and the item gets a cloud badge, but it stays fully available in iCloud — double-click it anytime to download it again.
If it still doesn’t work
Remove Download only appears for files inside iCloud Drive — it won’t show up for files stored only on your Mac, so move those into iCloud Drive first if you want them offloaded. Also give iCloud a few minutes to finish uploading before you remove the local copy; if the cloud badge never appears, check your connection.

Frequently Asked Questions
Does Remove Download delete my files permanently?
No. The file stays in iCloud Drive and remains accessible from all your devices. Only the local copy is removed to free up disk space; double-clicking the file downloads it again.
Why don’t I see the Remove Download option?
The option only appears for files stored in iCloud Drive. Make sure the file is synced (look for the cloud status icons in Finder) and that you’re right-clicking inside an iCloud Drive folder.
Conclusion
Between automatic optimization and the manual Remove Download command, iCloud Drive makes it easy to keep a full Mac running on a small drive. Enable Optimize Mac Storage once, offload your biggest folders by hand when you need space fast, and let the cloud do the heavy lifting.
