I have a referenced library of scanned travel images on an external drive that has now almost filled. How do I move this library to a new much larger external drive? I have experimented with one folder of photos by just dragging and dropping (it was actually copied). I then disconnected the original smaller drive and attempted to look at the images on the new drive. The images and metadata were there but when I went to the adjustments the ‘image offline’ message came up. I went into File> Relocate Originals but got the message that ‘unavailable original files cannot be relocated’. What should I be doing?
