I currently have two external hard drives where I have all my bird photos classified into folders by the name of the bird. There are more or less a hundred. I have one external hard drive where I import all the photos to and the other external where I backup the first external hard drive every night. They are getting full and I will soon have to purchase two more, but I was wondering how I could export all the folder hierarchy into the new external hard drive. It surely will be a chore to have to create each one again.
