Although it doesn't help you this time, you may want to consider setting the saves folder (and generatedworlds folder) for automatic backup so that you won't lose anything if you accidentally delete something or have a corrupted save. Though for corrupted saves, you'd need a backup that keeps at least a couple copies or doesn't replace the last backup right away since you might just replace your good backup with a corrupted backup.No hope then. 4 different recovery programs didn't find all the files.
