Copy That is designed to quickly copy content from your Photo Library to an external drive via a suitable Lightning adapter. By suitable, we mean a USB external drive with its own power source, or a flash drive with minimal power requirements. For our review, we successfully used the app with a cheap Lightning adapter that supports SD and microSD cards as well as USB drives.
