I cannot find some of my previous imports, where are they. In addition, when searching for them in my computer they are also missing. No I did not back up elsewhere. Has this happened to anyone else and how do I find them again? I found the edits that I exported so i am not nuts! Where are these files? HELP PLEASE?
Perhaps you accidentally created a new Lightroom catalog. Try File->Open Recent and open each of the catalogs at that menu item to see if you can find a catalog showing these photos.
When you search for the photos on your computer, you need to use your operating system's search feature, and then search by file name.
