   This is an example of a secure file deletion under Windows NT. Files dropped
on the window are opened and their size determined. Then a mapping object is
created from the file and it's mapped to memory. Once mapped, it's a simple
procedure to memset() the entire block and flush the view, removing any data
on the disk itself. Finally, the file is deleted.
