Best way to synchronize new folders from external drive?
I've added new folders to my external hard drive with new photos in them and I'm wondering the best way to get Lightroom Classic to recognize them. I'm trying to synchronize the parent folder but there are over 10,000 photos in total and the "synchronizing folder" dialogue box does not appear to be making any progress--it's just stuck as shown in the picture below. I can't tell if that's just because of the folder size or something else. Is there an easier way to do this?
