thanks to all for replies.
i have no idea how i would restore a file from this lot .Yes they did come from running scan check on faulty drive which the removal of has repaired the drive. As matter of interest it was not the C drive but he D data drive that was giving problems . It would cause PC to crash badly and i could not run defrag on it . Now i can. It was crashing when making slide show so i guess it was when D drive had to rush around looking for picts it met the bad sectors.
