After posting this question, I received a private message from a user called "Software Analyst 24x7", asking me for my Skype ID and phone number. They signed off "Adobe Help And Support". If you look at this persons profile, they registered on 20/January/2015... this seems very suspicious. If this is a malicious person, how do I go about reporting them to Adobe? Are Adobe even monitoring this type of behavior? Alternatively, if it really is Adobe support, surely they can present/identify themselves better?
Thanks dj_paige, but deleting com.adobe.Lightroom5.plist and restarting my computer did not make a difference. I also tried creating a new catalog and trying again, no change
According to your last screen shot, you have 7931 missing photos. LR calls a photo "missing" if it thinks there isn't an actual photo at the file location it's recorded in its catalog. This typically happens if you use the Finder to move a photo after importing it into LR, or if you disconnect an external drive. Have you done either? Try following the steps listed here.
This problem seems to be reported more and more in recent months, and in my observation, it is almost always reported for Mac computers (not Windows).
This sure seems like a bug, and I think people ought to start reporting it as a bug. So, thehurley, if you are so inclined, please report it.
This problem most likely occurs when there has been a case change in a path on disk. In other words (using the screenshot at the top of this post as an example), something like this:
intentionally or unintentionally gets changed to:
(i.e., "photographs" was initially lowercase, but got changed to an uppercase "Photographs")
As you've discovered, Lightroom does not handle this well. You can fix the problem by completely changing the path, and then updating Lightroom with the new path. Try these steps:
1. Quit Lightroom.
2. In the Finder (i.e., on disk, not in Lightroom), alter the path that your photos are stored at. In other words (again using the screenshot at the top of this post as an example), create a new folder called "Test" inside the "Pictures" folder, and then put the "Photographs" folder inside the "Test" folder, so that the new path looks like this:
4. Launch Lightroom. In the Folders panel in Lightroom, you should now see a question mark “?” on the “photographs” folder (and all the folders within it) because Lightroom doesn't know where they are any more.
5. Right-click on the “photographs” folder in the Folders panel in Lightroom, and choose “Find Missing Folder…” Direct Lightroom to the new location of the folder, i.e., /Users/hurley/Pictures/Test/Photographs. The folder, and the folders within it, should now be found, and the question marks should disappear from them in the Folders panel in Lightroom.
6. Now try importing again to see if the newly imported photos go into the right place.
