Hi. This sounds like a real simple solution. I've Linked missing files to their originals many times before. After restarting the app and my computer the problem still persists. I have multiple cameras in use in a catalog. After moving my files to my external, i have to relink the previews to the originals. Checking and unchecking the "Find Nearby Missing Photos" box does not work. I still have to link each (some 936) image individually. Does this sound odd to you? Please help!
The previews i'm trying to link come from a Sony camera. Oddly, a set of previews from another Sony camera (same model, different serial) link just fine. A set of previews from a Nikon camera also link just fine.
Thank you! This link you provided helped so much.
