How to compare 2 folders within Aperture 3
In an effort to manually remove duplicates and consolidate all of my aperture files in to one main library, I've got multiple folders that I need to compare to determine which files are missing from one versus the other. For instance, my file structure within Aperture is...
Folder (2015) > Folder (February) > Project (Trip)
Folder (2015) > Folder (February) > Project (Home)
....
So in this example. I have two "2015" folders where one is missing 2 files. I'm curious to find out what those files are but sorting manually through thousands of photos and folders is almost impossible. Any suggestions as to how to compare them to show me what 2 files are missing from the one folder that aren't in the other?
