My boss wants to have some sort of setup in place on his new WinXP laptop where he can put files in a location and have them encrypted. Company secrets and the like.

He does not want to secure the entire laptop. Other people may need to use the laptop with admin privileges while he is out of the office. So we cannot use WinXP user permissions or a boot password.

Free or cheap is good, too. Any suggestions on how to go about this?

Thank you!
