i really don't understand this question.
Why if you have deleted them, do you still require access to them.
if you hover over your trashcan (skin dependent) it should tell you the location of the trashcan. Maybe they are still showing in that location if you ftp into them.
If you just want an archive folder (watched folder), why don't you just create a new folder (menu botton), and then when you have watched stuff either move them (menu button again), or use ftp program to drag them into different folders.
