Lock and Hide Folder

A quick and easy way to protect sensitive information on your computer from children, employers, and anyone else who uses your computer, including law enforcement and hackers! This software will hide your sensitive files so that they can't be seen or accessed. Files stay hidden even if you turn on "View Hidden Files" in Windows folder options. Even links in your recent documents menu won't be able to find your hidden files! For extra security, use a password to prevent anyone from accessing your files. You can run this software in stealth mode so that no one knows it's there, and hide or show your sensitive files using hotkeys.
