I have files that say they are missing or offline. I have checked all my folders off of lightroom and they can not be found. I have used the ? mark settings to find and still not found. I can see the images on lightroom so they have to be in my system some how. How can I retrieve these images? Is there a re boot for lightroom? Need help ASAP!
You have probably moved the files outside of Lightroom. The images you see in LR are previews that were made before you moved the files.
Do a search for the files/folders using your computers operating system. (Explorer/Finder)
Once you have found them, you can point LR to the right location.
