Locked File Explorer is a file explorer designed for Android devices that restricts users to just whitelisted files and folders. This program, developed by 42Gears Mobility Systems, is free to use and falls under the Business & Productivity category. It offers restricted file access, as well as the import/export of configuration for mass deployment and branding support.

One thing to keep in mind is that for complete lockdown, the program must be used in conjunction with SureLock. During setup, permission usage and consent will be displayed, and the user must grant multiple special permissions. Overall, Locked File Explorer is a useful tool for businesses that need to restrict access to certain files and folders on their Android devices.
