Freeing up space · Caches and clutter
Does Storage Studio clear Safari, Chrome or Firefox caches?
Short answer: Yes. Free Up Space's cache step includes the disk caches of Safari, Chrome, Firefox, Brave and Edge. It never moves a browser's profile folder, which holds your cookies, sign-ins and history.
Yes — the cache step of Free Up Space includes the disk caches of Safari, Chrome, Firefox, Brave and Edge. That's the browser's stored copies of web pages and images, which it downloads again as needed.
It's the cache only. Storage Studio deliberately never moves a browser's whole profile folder — the part holding your cookies, saved sign-ins, history and open sessions — because that would sign you out of everything. See why it won't move your browser's folder.
You can untick any browser in the checklist if you'd rather leave its cache alone.
