How to Password Protect a Folder in Windows

Take a second to consider how much sensitive information you have stored on your computer at this moment. Bank information? Family photos? Financial documents?

As secure as your files feel on your PC, they’re also prime targets for malicious intent. Password protecting your sensitive folders is a basic security step. Think of it as a virtual vault, which encrypts whatever files or additional folders you’d need kept safe.

Read on to learn how to create a password-protected folder to keep your precious files protected, and sneaky onlookers at bay.

Method 1: Text-Based Folder Lock

While Windows 10 doesn’t allow users to password protect folders by default, you can use a batch script to lock folders using a password of your choice.

Start by navigating to the folder you’d like to lock. I’ll create a new folder to use as a virtual safe named Safe.

Double-click the folder. You’ll be creating your batch file within the directory that’ll store your locked folder. Create an empty text document within your folder by right-clicking an empty space and selecting New > Text Document.

Within this document, copy and paste the following code:

cls
@ECHO OFF
title Folder Locker
if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK
if NOT EXIST Locker goto MDLOCKER
:CONFIRM
echo Are you sure u want to Lock the folder(Y/N)
set/p "cho=>"
if %cho%==Y goto LOCK
if %cho%==y goto LOCK
if %cho%==n goto END
if %cho%==N goto END
echo Invalid choice.
goto CONFIRM
:LOCK
ren Locker "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
echo Folder locked
goto End
:UNLOCK
echo Enter password to Unlock folder
set/p "pass=>"
if NOT %pass%==your_password goto FAIL
attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Locker
echo Folder Unlocked successfully
goto End
:FAIL
echo Invalid password
goto end
:MDLOCKER
md Locker
echo Locker created successfully
goto End
:End

To set your password, change the your_password bit in the line if NOT “%pass%==your_password” goto FAIL to a password of your choice:

Once you’ve added your password, head to File > Save As within your Notepad program. Name it anything you’d like, Locker in my case, but ensure you add a .bat extension to your file. In my case, I will name my file Locker.bat (ensuring I’ve included the extension).

Double-click the BAT file to create your Locker folder. This is the folder that will be locked with your password. You should now have a folder and a file named Locker.

Place all your sensitive documents within this Locker folder. Once you’ve placed your files, double-click your Locker.bat file again. A command prompt will open asking if you want to lock your folder. Input Y and press Enter.

Poof! Your folder should disappear. This is a natural byproduct of your BAT file.

To access your files again, double-click on your Locker.bat file. You will be prompted to enter the password you added when creating the file.

Voila! If you enter your password correctly, your Locker folder will reappear again.

Note: This BAT file can be changed via your PC. That means others who are familiar with this trick may be able to change your password. For the most part, however, this nifty little trick will add a much needed buffer to your most sensitive local documents!
