Smart folder for photos
I am trying to create a smart folder that contains all my photos that are located in the masters subfolders that are held within the photo library that is stored on an external drive. I will then delete the photo library from my drive, but keep the photos. I have tried various combinations of searching, but can't seem to get the result I need. I hope this makes sense! Many thanks in advance for any help.
