Easy File Locker is FREEWARE.
Easy File Locker is a light-weight and easy-to-use file lock software product for Windows. It can protect your private files and folders. With its great protection, users will not be able to open, read, modify, delete, move, copy the locked files/folders, or even not be able to see it. The hidden files/folders will be totally invisible to all users and to any program.
Shadow Defender is an easy-to-use security solution (for Windows operating systems) that protects your PC/laptop real environment against malicious activity and unwanted changes.
Shadow Defender can run your system in a virtual environment called 'Shadow Mode'. 'Shadow Mode' redirects each system change to a virtual environment with no change to your real environment. If you experience malicious activity and/or unwanted changes, perform a reboot to restore your system back to its original state, as if nothing happened.
With Shadow Defender, you have the flexibility to specify which files and folders are permanently saved to the real environment. This ensures important files and folders are kept after a reboot.
