Deleting a file simply marks the occupied disk space as being available for
use by the file system for new files, but the physical content of the
original file still exists until it is overwritten later (the same applies
with memory as well).  The only way to do what you ask is to do what other
file shredding utilities already do - simply overwrite the current file
content with zeros (or garbage) prior to deleting the file.  That way, if
any file recovery tool tries to recover the file, all it will get back is
meaningless data.
