Cannot import photos to LR because they supposedly are already in the file. But they are NOT visible. Tried synch folder, no help. Photos are in a portable HD and are visible in Explorer. Must be another catalog somewhere? Need help, thanks.
The most likely explanation is that you ACCIDENTALLY imported the photos into a different folder than the one you are looking at.
This can happen if you choose COPY (again, accidentally) when you Import.
So the photos are in your catalog, just in a different folder, and you have to find them. To find them, please do all 4 of these steps, in order
Thank you Mr paige, simple enough, all photos found
