If you move image files in the Finder (Mac OS) or Explorer (Windows), the link between the files and the Lightroom Classic catalog breaks. When a catalog can't find a photo, Lightroom Classic displays a Photo Is Missing icon () in image cells in the Grid view and the Filmstrip. In the Develop module, Lightroom Classic indicates that the photo could not be found, or is offline or missing.
Follow the steps below to help locate your missing photos and restore links to the catalog.
Links between a catalog and its photos can also break if photos are stored on an external drive that is offline. If the drive is offline, turn it on. If the drive letter has changed, change it back to the letter Lightroom Classic expects.
(Optional) In the Locate dialog box, select Find Nearby Missing Photos to have Lightroom Classic search for other missing photos in the folder and reconnect them as well.
If an entire folder of photos is missing — the folder is dim in the Folders panel and has a question mark icon () — you can relink all the photos at once by right-clicking (Windows) or Control-clicking (Mac OS) on the folder and choosing Find Missing Folder from the context menu. See Locate missing folders.
