Freeing up space · One-tap clean-up (Run Tuhi)
Does Run Tuhi empty my Trash to free up space?
Short answer: No. Run Tuhi never empties your Trash, whatever your settings. It's the one clean-up that can't be undone, so it stays your decision — empty it from Finder when you're sure.
No. Emptying the Trash is never part of a Run Tuhi clean-up, regardless of your settings. It's the one action that permanently removes your own files with no way back, so Storage Studio leaves that decision to you.
Everything else the run does either rebuilds by itself (caches, logs) or can be reversed (moves to your fast drive). When you're sure you no longer need what's in the Trash, empty it from Finder, where macOS shows its own warning first.
Emergency Space follows the same rule: it tells you how much is sitting in the Trash and lets you open it, but never empties it for you. See Will Emergency Space empty my Trash?.
