I am a Lightroom Classic user trying to learn how to use Lightroom CC and can't understand how to BATCH rename files. As in... change the name of the files wherever they are stored. I am trying to follow the instructions in this article - https://havecamerawilltravel.com/lightroom/how-to-batch-rename-photo-filenames-in-lightroom/ but my Lightroom CC desktop version's control panel looks completely different. The "file" field is greyed out on my desktop version. Btw, I'm also having trouble re-arranging images using the film strip. Something is wrong with the "grippy-ness" of the double click so I can highlight the file I want to move but cannot make the "black bar between images" appear. So I can't release it anywhere. Thanks for any help you can give me. I'm busy with work so I can't afford the time to switch to Lightroom CC but wanted to see if I can do perform some basic functions. So far, it's going badly. Thanks.
