FWIW, the presence of a metadata.db does not say a whole lot.

If Calibre assumes a library exists at a certain location, and on launch finds there is nothing there, it will simply create a blank metadata.db.

So if something happened to your library between closing Calibre and reopening it, that caused all of the epubs to go awol including the metadata.db, then anything found after relaunching Calibre is trash fodder. Can't nothing be done with no more. Only option is having a backup or a tremendous heap of luck trying to recover with a recovery program if files were deleted (leaving in the middle how they might have gotten deleted)

From the sound of it the complete folder structure was still there, just no more epub files. Any covers or opf files still present? .original_epub's even? If these are still there ... You the only one with access to that computer?
