Moving folders · Data Parking (the two-pane mover)
How do I delete a file or folder from Data Parking, and why does it ask me to type DELETE?
Short answer: Right-click and choose Delete…, then type DELETE and solve a one-digit sum to enable the button. It's careful on purpose: local deletes here skip the Trash, and cloud deletes may be permanent depending on the service.
Right-click the item and choose Delete…. A two-step confirmation opens: type the word DELETE and solve a tiny one-digit sum, and only then does the delete button enable. It's deliberately careful because this delete is permanent for local items.
The sheet shows where the item is, whether it's local or in a cloud account, and how recoverable it is: local deletes skip the Trash, and cloud deletes are permanent on some services and land in the provider's own trash on others. It reports Done or the error in the sheet, and you close it yourself so you can't miss the outcome.
If you only want the space back, moving is usually the better choice. See Why move instead of delete?
