Koken export original images
Koken organizes photos in Albums (and Sets), The original uploaded photos are stored in an obscure folder structure like:
Every uploaded photo has two unique subfolders in the koken storage. Impossible to see what goes where from Finder or FileExplorer.
A set of folders and files in the structure of Koken is needed for offline viewing on digital image frames and photoviewers on tablets, smartphones, TV's etc. etc. In my case Plex. Or just as a backup.
