Folder Castle is a Windows application designed to enhance security and privacy by enabling users to control access to specific files and directories through encryption and hiding features. Integrated seamlessly with Windows File Explorer, this program simplifies the process of protecting files and folders with just a few clicks, accessible from both the toolbar and the file context menu.

To ensure secure operations, Folder Castle mandates the use of an administrator password set during installation. This password grants access to all protected files, adding an extra layer of security to sensitive data. Additionally, users can leverage Folder Castle to create an encrypted virtual storage unit for storing critical files securely.
