The procedures above delete only the initial part of the data used for file
management. This makes the file invisible to the operating system, but
the data can still be read by specialized utilities. If you dispose of the

unauthorized use of such data. To ensure your data is not used for
unauthorized purposes, you can:
Physically destroy the hard disk drive
Use a proven specialized utility to overwrite all data
Take the hard disk drive to a professional deletion service
