# Does a shared iCloud Drive folder use my storage or the other person's?

The **owner's**. Everything in a shared folder counts toward the iCloud storage of the person who created and shared it, not the people invited. If the owner's iCloud is full, the shared folder stops syncing new changes for everyone.

On each person's **Mac**, though, downloaded copies of shared files use that Mac's own disk like any iCloud Drive file — and they can be made online-only to save space. See [online-only iCloud files](https://storagestudio.us/faq/icloud/what-does-online-only-mean-for-icloud-files).
