How to Password Protect a Folder without Any Software in Windows

In our daily work, we usually need to encrypt various files. It’s easy to set password for Office/PDF/archive files. But, some types of files don’t support password encryption. In this case, a good idea is putting the files into one folder and then password protecting the entire folder. Now the problem is how to put password to folder. You might think you couldn’t do without some third-party software. Actually, it’s not. You can password protect a folder without any software in Windows.
