Moving folders · Rules and Auto Rules
How do I preview what my rules will move before they run?
Short answer: Click Dry Run in the menu bar popover, or Run preview in the Rules window. It lists exactly what your rules would move or clean, with sizes, without changing anything.
Click Dry Run in the menu bar popover, or open the Rules window and click Run preview in its bottom pane. You'll see exactly which items the rules would touch, their sizes, and whether each would be moved or cleaned. Nothing is changed.
It's the safe way to check a rule change before it takes effect. If the preview shows something you don't want moved, adjust the rule in Settings → Rules and run the preview again.
