Thank you, I discovered a bunch of dupes I didn't know I had, and was able to merge them. Much appreciated!
However, a lot of recent dupes did not show up with that method.
I was taking a lot of photos and videos last month with my iPhone 13 Pro camera app. I had accidentally selected the "live" function, so I have a lot of photos with a "dupe" 2-second video file.
In addition, I had selected one of the color effects ("dramatic warm") and so I have a dupe version--one original, one dramatic warm--of each file too.
So I have four versions of each photo and also several versions of each video I took for about a week or so last month.
On my iPhone in the camera library, I just see one image or video, but the multiple files all show up when I import to Adobe Lightroom Classic.
For whatever reason, these recent ones didn't show up in Photos using the method you suggested.
I'm looking for a quick way to sort through and merge these recent multiple files, or to delete the dupes.
Being able to bulk select which of the multiple files to keep (usually the original, on occasion--such as during some geisha dances--the live image) would be awesome too.
Thank you in advance.
