After highlighting an empty file folder and its subordinate empty folder and hitting DELETE, my entire file structure disappeared. "All Photographs" indicates all the photos still exist. However there is no file structure at all under "Folders". Any ideas on how resurrect the file structure?
Try switching from the Catalog tab to the Folders tab and right-clicking on the parent (top-level folder) in the folders panel and choosing “Update folder Location”
Normally you can re-link files with the catalog in this way.

Thanks so much for your help. It worked.
