Hex Editor
You can use a hexadecimal (hex) editor to view the hex representation of a file or a graphic
image. One such hex editor is XVI32, developed by Christian Maas and available at no cost at
the following URL:
http://www.chmaas.handshake.de/delphi/freeware/xvi32/xvi32.htm
For example, if there is a certain graphic contained within all confidential company documents,
you could use the hex editor to obtain a unique identifier for the graphic, and then use the
identifying hex string to create a match object. You could reference the match object in a policy
that blocks the transfer of files with content matching that graphic.
