Have you checked the Recycle Bin on your computer? You might be able to recover the folders.
You might try a hard reset. I'm not sure if that will recreate all the files but, it's worth a shot.
Try doing a firmware upgrade. Check Sony's site for the firmware installer and that should write all the required files.
