Explanation:

The end users can protect the folder by enabling encrypt the folder or files. But in windows encrypting the file or folder is not available. The computer management console is used to open all other services such as risk management, performance management extra.

In some other operating encryption of folder or files is allowed.  Third-party software is available to protect folder or files once the third party used any files possible to share outside the world.
