Blank And Secure is a portable tool to securely delete data. Securely deleting files is 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.
