Help keeping files hidden?

Put them all in one folder, put the folder on the desktop, then right click that folder, go to Properties, then under Attributes, select 'Hidden.' To unhide it, it depends on what operating system you're running - something you're clearly confused about. In Vista, It's under control panel --> appearance and personalization --> folder options --> show hidden files and folders. You can also pword-protect, encrypt, or obfue them in some other manner, but then he'll know you're up to something. Easiest solution is just to put the folder on your own USB Flash Drive and then hide it.
