This is the software publisher's description.

Free Wipe Wizard erases private and files and wipes sensitive information in a secure manner. We guarantee that the file erased with Free Wipe Wizard can never be recovered with any other tool. Even if your disk lands in the hands of F.B.I. your erased information remains inaccessible. The erased information will hold secure even if special methods are used to sense weak magnetic information off your hard disk surface!

Free Wipe Wizard is fully functional and free of charge. The tool takes care of your files in a simple and efficient manner. Just run the tool, select a file to delete and click "Delete File" to wipe off its content forever. No data recovery tool can ever restore the contents of your file - guaranteed!

Anyone can guarantee 'complete confidentiality' or 'ultimate security'. The question is whether or not they are ready to back their claim. We are completely confident in our software because we used the US Government standard seven-pass wiping to overwrite your data in a theoretically proven, completely tested, cryptographically secure way. A cryptographically strong sequence of random numbers is generated for each wipe, making it absolutely impossible to access the erased information even if your hard drive is disassembled and viewed under an electronic microscope. Needless to say that any software tools for data recovery will pass on data deleted with Free Wipe Wizard.

Not all implementations of secure file delete are equal. Some are just using zeroes to wipe your data, and some are using weak random key generators. While these tools defeat software-based data recovery utilities, they fail to provide the ultimate data security that only a proper tool can guarantee.

Free Wipe Wizard is based on a cryptographically strong open-source code, and is distributed with GNU General Public License.
