Window 10 Pro; latest LR classic updates. I have an external SS drive containing the LR catalog, and all other necessary LR files: Previews, Backups, and Camera Originals. All works well when plugged into my laptop. When the same external drive is plugged into my desktop, I get the ! “Original File Cannot be Found” on all thumbnails. I know how to tell LR to locate one file and then all other in the same location. However, with 34,000+ images that takes close to one hour. So the first question is, since the entire LR catalog, all its components and the original camera files are all on the same hard drive, why must one go through this when moving from one computer to another? Also, rather than FIND MISSING PHOTOS, I tried to tell, through LR, where the folder is that contains the Originals. If I look in LR at the folder that contains all the Originals, it does NOT show the question mark ?, but rather indicates that there are 0 images in that folder. So using the context menu for that folder, I select “Update Folder Location”, navigate to that location, click “Select Folder”, wait for an hour and NOTHING happens; folder still shows 0 images, and individual images still indicate the exclamation symbol ! I also tried “Synchronize Folder.” I Unchecked “Import New Photos (35,892) but SHOW MISSING PHOTOS is grayed out, and clicking on SYNCHRONIZE does nothing. Any idea as to why this happens, and how I can work between my laptop and desktop without waiting over an hour to eliminate 34,000+ exclamation marks. Many thanks for any insight you can provide. Lester.
