4 best ways to hide or protect a Windows folder, without installing additional software

There are many ways to protect sensitive folders and data, such as hiding them in hard-to-find places, storing them in removable storage devices and putting them in safes, and storing them in the cloud with strong passwords. But if you have to access them frequently, you will have to leave them on your computer, even in the most accessible places. In that case, a more effective way to protect folders is to hide them, set a password, or encrypt them.

In the article below, WebTech360 will guide you through 5 ways to protect folders on Windows:

1. Hide any folder using Windows built-in option

Windows has a built-in tool that allows you to hide folders that you want to hide. This is a low-security method and should not be used to protect important data. You can also use this tool to hide folders that you find annoying.

How to do as follows:

1. Go to File Explorer and find the folder you want to hide.
2. Right-click on the folder and select Properties (on Windows 11, select Show more options > Properties )
3. Click on the "Hidden" box and press OK

To view the files again, all you need to do is on the Folder Options window , uncheck the items Show hidden files, folders, and drives and Hide protected operating system files . Or you can click on the " Hidden items " box in the View menu of File Explorer.

2. Turn a normal folder into a hidden system folder using Command Prompt

Command Prompt is a command-line interpreter application available in most Windows operating systems. It is used to execute entered commands. Most of these commands automate tasks through scripts and batch files, perform advanced administrative functions, and troubleshoot or resolve certain types of Windows issues.

Command Prompt's official name is Windows Command Processor, but it's sometimes referred to as the command shell, or even by its file name, cmd.exe.

Turning a regular folder into a hidden system folder using Command Prompt is a bit more difficult than the previous method, so of course the security will be higher. To do it successfully, you will have to manipulate a bit with the Command Prompt command line window.

How to do as follows:

1. Press Win + R to open Run then type cmd and Enter to open Command Prompt
2. Type the following command into Command Prompt:

   attrib +s +h “C:\Users\Quantrimang\Desktop\Bi Mat”

3. Replace C:\Users\Quantrimang\Desktop\Bi Mat with the path to the folder you want to hide. For example: D:\TaiLieuTiengNhat
4. After completing the command, press Enter and the folder will be hidden. Even if you unhide it in Folders Options, it cannot be found.
5. To unhide, you need to run the above command again but replace the " + " with a " - "

3. Encrypt files or folders without installing additional software

Encryption is an effective way to protect your files. Microsoft includes an encryption tool in Windows that makes it easy to protect your data.

How to do as follows:

1. Right click on the file or folder to encrypt and select Properties
2. Click the Advanced button
3. Click on Encrypt Contents to Secure Data and then click OK
4. Click Apply to finish
5. If you encrypt a file, the system will prompt you to encrypt both the file and its parent directory.
6. After encryption, the file or folder will turn green.

The only downside to this method is that it ties the encryption to your user account. This means that other accounts on the same computer will not be able to open the files or folders you encrypted. However, if you share an account, this method will not work.
