Moving folders · Data Parking (the two-pane mover)
Why did Data Parking reopen with my folders already paired?
Short answer: Storage Studio remembers the pairings you've used and restores them so you can carry on where you left off. Click Unpair or Home both to start fresh, and pin favourites in the Recent list.
Because Storage Studio remembers pairings you've used and restores them automatically, so you can pick up where you left off. If you'd rather start fresh, click Unpair, or press Home both; a deliberate unpair is respected.
To jump between pairings you use often, pin them in the Recent list. See What are Recent pairings?
