Here is a tiny, portable tool for deleting data permanently from your hard disk. The free tool called ‘Blank And Secure’ overwrites the data with zeros before deleting it, so recovering became impossible.
Using Blank And Secure is very easy. Run the program, drag and drop files and folder into it. Select overwrite times (Overwrite the data X times with NULL), and click delete button, that’s all.
For a security reason, this type of tool is necessary. It allows users to completely remove sensitive data from their hard drive by overwriting it several times. Download Blank And Secure
