# Can I stop Optimize Cloud Storage while it's working on a cloud folder?

Yes. The progress window has a cancel option, and stopping partway is safe. Files already made online-only stay in iCloud and download when you open them; files not reached yet simply stay downloaded.

Nothing is half-finished in a harmful way, because making a file online-only is never a delete — each file is either still local or safely in the cloud. You can run the pass again later to finish the job.

On a large iCloud Drive the pass can take a few minutes. Storage Studio paces its background work so your Mac stays responsive while it runs.
