And also consider that the destination of the drag could be a different app, in which case you don’t get an -acceptDrop: call at all. Instead, to handle the source end of a move (or delete, i.e. drag to Trash) you need to implement the NSDraggingSource protocol’s -draggedImage:endedAt:operation: method. If the operation was a move or delete, you should delete the dragged items. —Jens
