Blank And Secure Product: Blank And Secure Website: www.softwareok.com Type: Free Requirements: Windows XP/Vista/7 "Blank And Secure" is a portable tool to securely delete the data. Securely deleted files are required to block the recovering of deleted data. Secure deletion is possible with this program, because "Blank And Secure" overwrites the data with zeros before deleting. The data recovery is impossible after this operation. So please only use if the data really should be permanently deleted. The other overwriting standards such as US DoD 5220.22-M ECE, German standard and Peter Gutmann standard is not implemented, because in tests, the results had no measurable improvement, for that reason it is not implemented in "Blank And Secure".
