Why can't I empty or move the Trash from What's Using Space?
Short answer: Emptying the Trash is the one thing Storage Studio can't undo, so What's Using Space shows its size but offers no button. When you've decided, use Free Up Space or empty it in Finder.
Because emptying the Trash is the one action Storage Studio can't undo, so it isn't offered on a screen you opened to find out where your space went. The Trash's size is still shown — that's useful information — but the decision stays yours.
When you've decided, use Free Up Space, or empty the Trash in Finder. Everything else Storage Studio removes goes to the Recycle Vault first so it can be put back.
