I've watched several videos of others showing how to archive photos within Lightroom so everything is well organized and your photos don't get misplaced and you have to find them. I added a folder of the external hard drive so it would show within Lightroom. I built smart previews for the photos. However when I try to drag a catalog into the external hard drive in Lightroom, nothing happens. On the videos, you can see the photos physically being moved to be archived. Not sure what I'm doing wrong or if there's an underlying issue. Any help is greatly appreciated!
