I import files into Lightroom from an external hard drive. Most of the time, the files appear in Lightroom as part of the folder that is on the external drive. Today, some of those files were duplicated in a new dated folder on my laptop. For those files, Lightroom links only to the new folder. How do I get Lightroom to find the files in their original folder so all the files from the same folder appear together in Lightroom?
