I am having trouble with Aperture 3. I was using picasa before, and have all my photos in the Pictures folder sorted by year and date taken. I installed Aperture and imported the folders as projects, and clicked Move instead of copy (I think). When I selected a photo I wanted to delete, and went to File-Delete Master Image and Versions, and deleted the file and emptied the Aperture trash, the file was still on my Hard drive in the pictures folder. What do I need to do to permanently remove a picture or video in Aperture?
