In the middle of importing thousands of images, I accidentally changed the setting that copied the original files from the external drive to the computer's hard drive. The result: about 45% of the files in the library are on the C drive of my machine and about 65% are on the external drive. I have added keywords and facial recognition to ALL of the files. Is there a way to get the files from the external drive to the C drive and maintain the metadata?
In the Folders panel of the Library module drag and drop the folders/files where you want them to be. Just make sure Lightroom does the moving and not Finder/Explorer.
