While Windows makes it easy to hide/unhide files and folders, it does not provide any option to password protect files and folders.
Hence, the only way to protect Files and Folders on a Windows 10/11 computer is to hide the File/Folder, unless you are using the Professional Edition of Windows, which also provides the option to Encrypt Files/Folders.
However, there are a number of third-party tools and software programs that can be used to password protect files and folders on both Home & Professional Edition of Windows.
