MySecretFolder is a Windows utility that transforms any standard folder into a password-protected and invisible folder to other users of the system. After installation, the setup wizard guides the user to select the folder to protect, set a password, and activate the protection. Once protected, the folder no longer appears in Windows Explorer, applications, or command-line tools, remaining hidden until the authorized user enters the password to unlock it. The program includes a free 30-day trial period with no functional restrictions, and its uninstallation is performed through the standard Windows Control Panel.
