I don't understand. I think in a "Choose File" Dialog you can pick multiple items. And as far as I know folders are mixed with files on the list (that's how you navigate between folders on this dialog).
Why not choose multiple files/folders? Security doesn't seem to be a concern. I can make a mess with only one folder.
