"Blank And Secure" is a portable tool to securely delete the data.
Secure delete 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 my test i had no measurable improvement, for that reason is that not implemented in "Blank And Secure"
