My computer froze and when I restarted it. The catalog I was working on was gone. I tried to re open it, but non of my edited pictures where saved. I had to export all the pictures agai but no work was saved. Is there a way to find all that work again.?
Open Lightroom, go to File->Open Recent and select each of the catalogs listed there until you find your work.
I've tried to do that and all the Pictures where there but not edited.
Use your operating system to search all of your hard drives for files ending with .LRCAT. Open each one by double-clicking on it until you find the catalog of interest.
