# Why hasn't Optimize Mac Storage freed any space yet?

Because macOS only frees iCloud files when it decides it needs the room — typically when free space is running low — and it starts with files you haven't opened for a while. Turning the setting on doesn't free anything immediately.

If you need the space now:

1. Tap **Run Tuhi** in Storage Studio. Its cloud step makes large downloaded files online-only straight away and shows how much it freed.
2. Or right-click a large folder in iCloud Drive in Finder and choose **Remove Download**.

Either way the files stay in iCloud and download again when you open them.
