Moving photos to external HDD
My Catalogue is on an external drive. I have inadvertantly imported photos to my internal SSD which is now nearly full. So I want to move the photos from the SSD to the External HDD, keep them in my catalogue, to free up space on my SSD. When I use "import" and highlight the files they appear grey out, and LR telll me they are already in my calologue. How can I move them, please.
