How To Protect Files And Folders In Windows 10


The ability to protect a file or folder is an important feature of the Windows family. The Windows 10 feature that allows us to protect a file or folder is also quite helpful for protecting our documents from fraudsters.

If we happen to have to share our laptop with another person and we do not want to share our documents with him/her, we can safeguard our papers using a number of methods, including modifying a file or folder’s permissions, utilising command prompt (Cmd), and using any third-party programme.

This guide will demonstrate several methods for protecting your files and folders in Windows 10.
