How to: hide any file in Windows Vista

My Lockbox

My Lockbox is a free utility that will securely hide your files from prying eyes. You do this by placing the files and folders inside a special folder called a lockbox. This remains hidden from all users and software on your system, including both the Administrator and System accounts. It also remains hidden from Vista itself. Without the password to open it, it's also impossible for other people using your account to see its contents.
