Privacy & safety · Keeping your files safe
Will Emergency Space delete important files when my disk is full?
Short answer: No. You choose how much room you need and it picks the smallest, safest set of actions, starting with space that returns without deleting anything. Nothing destructive is pre-ticked, and removals stay recoverable in the Recycle Vault.
No. You say how much room you need, and Storage Studio picks the smallest, safest set of actions to get there — then stops. Options are ordered by what they cost you: space that comes back without deleting anything first, then things moved to your drive and still available, then files apps simply rebuild, and only then anything deliberate.
Nothing destructive is ever ticked for you, however tight things look, and deletions still go to the Recycle Vault. Afterwards it measures what actually came back and tells you if it fell short. See Free Up Space.
