I presume that you finish the user drag/drop cycle in MouseUp event of Listbox containign folder names. So you have to prolong the 'cycle' and 'click mouse' (use MOUSE command) immediately in the same snippet. After this you have to check click event (if fired) and get selected item IndexId which you will use to identify folder.
