Why won't Storage Studio move my browser's folder?
Short answer: Moving a browser's folder would take your cookies, sign-ins, history and sessions with it, and break whenever the drive is unplugged; some browsers even delete the link. Storage Studio leaves them alone. Clearing the browser's cache is the safer fix.
Because moving it wholesale would take your cookies, saved sign-ins, history and open sessions with it — you'd be signed out of everything, and none of it would be reachable whenever the drive was unplugged. Some browsers also delete the link left behind when they reset their cache, which quietly undoes the move.
Storage Studio recognises these folders by what's inside them rather than by which browser made them, so the rule holds for any browser, including new ones.
If the browser's space is mostly cache, clearing caches is the right fix — the browser rebuilds them. See freeing space.
