Deleting files using the delete or cut command do not really remove the files physically from your hard disk or other media storage devices like USB flash drive. Files are unknowingly still intact and just waiting to be restored back using the restore capability of an operating system or using third party utilities for files that cannot be recovered by the operating system.  This is usually the reason why a lot of computer users, who thought that they have deleted their files, fall victim of compromising their privacy and confidentiality data.

Here are reliable ways of completely deleting old and confidential data and protecting them from being recovered back.

1. Use DBAN. Darik’s Boot and Nuke (DBAN) is a self-contained boot disk that securely wipes the hard disks of most computers.
