Trying to upgrade my laptop HD and the copy program (EZGig) comes up with this error and stops. Have run Scandisk dozens of times both in Windows and DOS. Windows Scandisk says it's OK now, but DOS Scandisk says there's still one or more invalid long filenames, but can't tell me which file it is. Have browsed through the whole directory structure but too many possibilites. Anyone know another method to find these long filenames and delete or fix them?
