I wanted to move some photos to my Western Digital My Cloud drive (external storage). This just never goes away. How to I stop the process? How to I find what pictures I was moving and "deselect" them from this process. Very novice here so thanks in advance for any help!
Are you doing this from inside Lightroom? The screen shot isn't definitive perhaps.
That is to say are they in a LR catalog already?
You move the photos using your operating system, and then reconnect in Lightroom via these instructions: Adobe Lightroom - Find moved or missing files and folders
HINT: next time, put the photos on the external drive straight out of the camera, and then you won't have to move them at all.
