Camouflage is a free utility that will hide your personal or confidential files within another file. The neat thing is that the container file looks and works like a normal file of that format. So, by way of example, you could embed a secret message in a Word file which could be opened by anyone and would appear to be just a normal Word file. The intended recipient could use his or her copy of Camouflage to open the file, enter the password and extract the embedded information.

This free program is not intended to provide military strength protection, but it does provide a convenient way to sneak information past unnecessarily prying eyes. Note: It looks like the author's web site is down; however you can download Camouflage from the other links below. (2.65MB)
