I am looking for a way to list or filter out the photos that are reported as missing or offline. I have seen at least two photos in Library with a question mark. The folder itself didn't have a question mark and not all of the photos in the folder had the question mark. I thought I would fix it later. But now I can't locate that particular photo in Library because I have many folders and about 7400 photos to go through to locate that particular photo or photos with question marks.
There must be a better way! Is there no way to filter missing or offline photos in Lightroom? I mean the same way you would filter photos with a particular flag, rating or color label? You just go to Library, click Attribute, and then click on one of the flag icons (picked/unflagged/rejected) and Lightroom will show you the photos with those attributes. Can you do something like that for missing photos (i.e. photos with a question mark)?
