I made a terrible mistake. I (1) imported files from camera into my main folder named "My Lightroom." Next, I decided to change "My Lightroom" to My LR Photos." Bottom line the photos I imported to Lightroom and all of the photos that were in "My Lightroom" have broken links because of the name change. Is there a way to find the original "My Lightroom" so that I can restore the links without having to find and restore the links of over 3,000 photos?
Either rename the folder back to "My Lightroom", using Explorer/Finder,
in Lightroom, right click the My Lightroom folder, and point LR to the "My LR Photos" folder.
In the future, always rename folders within LR.
