The Notepad Trick: How to Lock PC Folder Without Any Software

Now let’s get to our main tutorial. This trick is nothing short of magic, and in it we’ll smartly use Windows’ built-in Notepad and Command Prompt (CMD) system. If you’re wondering how it’s possible to hide a folder on your PC using CMD, just follow the steps given below exactly:

Step 1: Create a New Folder and Open Notepad

• First, right-click on an empty space on your Desktop or on any drive, like C: or D:.
• Then, click on New, then on Folder, and give this folder any name, such as “My Projects”.
• Now, double-click the folder to open it. Then, right-click on the empty space again, click New, and select Text Document. A Notepad file will open.
• Then, copy the secret code given below from here and paste it into your empty Notepad file:

cls
@ECHO OFF
title Folder Locker
if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK
if NOT EXIST Private goto MDLOCKER
:CONFIRM
echo Are you sure you 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 Private "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-Here goto FAIL
attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Private
echo Folder Unlocked successfully
goto End
:FAIL
echo Invalid password
goto end
:MDLOCKER
md Private
echo Private created successfully
goto End
:End

Use code with caution.

Step 2: Set Your Secret Password

After pasting the code, if you read this Notepad file carefully, you will see this sentence written on around the 23rd line:

if NOT %pass%==Your-Password-Here goto FAIL

You just need to remove the words “Your-Password-Here” from this line and replace them with your new password, without any spaces. Let’s say your password is “Tech123,” then the line will look something like this: if NOT %pass%==Tech123 goto FAIL. This process makes it completely clear how easy it is to lock a PC folder without any software, because the password is saved in your own system’s file, not on any online server.

Step 3: Save the File with a ‘.bat’ Extension (The Most Important Step)

This step is the most crucial part of this entire bat file code to lock folder trick. If you save it as a normal text file, this trick will not work at all.

• After setting your password in Notepad, click ‘File’ in the top-left corner and select ‘Save As…’.
• Now, in the small window that opens, change the ‘Save as type’ option from “Text Documents (*.txt)” to “All Files”.
• Now, in the File name field, type: FolderLocker.bat. It is very important to add the .bat extension, so do not forget it.
• And then finally, click the ‘Save’ button. Now you can delete the old Notepad file.

This is a small Batch Script file. If you want to know practically how these scripts run commands in Windows, you should definitely check the official Windows Batch Scripting guide on Microsoft Docs. This is a trusted Microsoft resource that confirms this method of locking a folder using Notepad is 100% genuine and completely safe for your PC.
