I'm trying to reorganize my Aperture set-up and ran into a bit of trouble. I was using an organization system based upon Projects but after reading this I decided I wanted to emulate the date based folders. Currently, the project on the top of my tree is entitled "2008 04 05". I want to move those images to a structure similar to the article linked above. So, I need a Blue Folder named "2008" with a sub-Blue Folder named "04 - April". I created these blue folders and just figured I could select the images in the old "2008 04 05" Project into the new Blue Folder. Not so fast. Aperture won't let me drag photos from a Project to a Blue Folder located outside that Project. So, how do I do this? Would it be better to dump my current library and start over with the new organization scheme? If so, how do I go about that? Thanks in advance.
