Hope readers are having a good day.
Via a series of events that that don't help to describe - as the fact is that what happened has happened - I have lost the pointers to the referenced files in my primary Capture One 7 Catalog.
The missing references show with the standard exclamation point and the message "The selected image is either unavailable, in an unsupported format, or corrupted".
The referenced files have not changed folder location or drive letter. They remain exactly where they were before the problem occurred.
The user collections where the problems reside have a mixture of "located in C1 7 catalog" and referenced images. Only the referenced images have the issue.
I can fix each issue one by one by right clicking each problem image separately, specifying "Locate", and then pointing to the correct file in the Explorer window that is part of the Locate function. If the newly linked file has had adjustments and/or has been processed from RAW to jpg - all of those adjustments and indicators reappear and all is well. As you might expect, the newly linked images once again appear in the Folder section at the bottom of the Library view. None of the remaining problem images are showing in Folders.
It doesn't help to go back to a prior Catalog backup. I went as far as to restore the entire Capture One Catalog folder using an Acronis backup that preceded the events that caused the problem to begin with. For whatever reason, C1 7 thinks those referenced files have moved, and I'm reasonably certain that the only fix that retains adjustments is to reestablish the links.
So the question is whether I'm stuck re-linking every problem image separately, or whether there's a way to re-link them in larger groups.
Or, is there a related magic process that I haven't found yet?
Just for grins, I created a current backup of the Catalog file, and "Integrity Check" didn't notify me of any problems.
