You can try unzip the Lightroom backup folder's and look for the Lightroom catalog file with the extension .Lrcat
However if you successful to open any one of the latest backup file in Lightroom the images still have the question mark since you have changed the folder name on the hard drive.
Please refer the link to re-link you images in Lightroom catalog : How to find missing photos in Photoshop Lightroom
Mohit, Thanks for your reply.
I basically had roughly 50 picture folders. I consolidated these into 3 new folders on the Mac's drive (big mistake...). Keep in mind that these 50 or so folder names have not been changed. But by re-importing into LR these 3 newly consolidated folders, all of the previous 50 folders with the question mark symbol (broken link) disappeared, so it's impossible to do a "find missing folder" operation now.
Do you know of a way to perhaps reverse an import to go back to the way it was before? And if so, will I see again these folders with broken links and then be able to use the "Find missing folder" feature? If I change back the Picture folder on my hard drive (re-create it to its original structure) would it work, or will I complicate things further more?
Download "Stuffit Expander" to unzip your catalog file. Then open it up in Lightroom and you'll have your last saved catalog.

You can only restore a backup catalog from a zip backup.
Follow the advice at this link (adding the need to UNZIP the backup first.)
And if so, will I see again these folders with broken links
Yes. The restored catalog will still contain the folder links as they were before you moved them.
and then be able to use the "Find missing folder" feature?
No. Because the "Folders" no longer exist where Lightroom believes them to be. You condensed the 50 into 3. Lightroom cannot know what you did.
If I change back the Picture folder on my hard drive (re-create it to its original structure) would it work,
Yes, and this is the only way it will work.
If you had another HDD with a full (50) folder backup of all the photo folders as they existed before (~50), then a simple copy and paste would restore the folder structure from that backup. (One reason why I keep a regular "Mirror" backup of all my image folders.)
or will I complicate things further more?
No more than it is already.
Lesson learned: Never do anything to your image files and folders outside of Lightroom!
And Re-importing or synchronizing folders will NOT help, but just make matters worse.
