🔐 Folder Lock & Unlock in Windows

A lightweight, portable Batch script to lock (hide) and unlock folders on Windows without installing any third-party software.

⚠️ Important Disclaimer: This tool uses a system trick (renaming to a CLSID) to hide the folder. It provides basic privacy against casual snooping but does not encrypt your files. A tech-savvy user can still access the files if they know where to look. Do not use this for highly sensitive data like banking details.

Warning

Educational Use Only

✨ Key Features

• No Installation Required: Works directly on any Windows PC.
• Password Protection: Simple text-based password system.
• Stealth Mode: Completely hides the folder from standard Windows Explorer views.
• Fast & Lightweight: Zero background processes or memory usage.

🛠️ How to Use

1. Download & Setup

1. Clone this repository or Download the Locker.bat file.

   git clone https://github.com/hackerstoreofficial/Folder-Lock-Unlock-in-Windows.git

2. Place the Locker.bat file in the directory where you want your locked folder to exist.

2. Set Your Password

1. Right-click Locker.bat and select Edit (or Open with Notepad).
2. Find the line that says:

   if NOT %pass%==YOUR_PASSWORD_HERE goto FAIL

3. Replace YOUR_PASSWORD_HERE with your desired password.
4. Save the file (Ctrl + S).

3. Locking & Unlocking

1. Create Locker: Double-click Locker.bat. A new folder named Locker will appear.
2. Add Files: Move your private files into the Locker folder.
3. Lock: Double-click Locker.bat again. Type Y and press Enter. The folder will vanish.
4. Unlock: Double-click Locker.bat. Enter your password to reveal the folder.

📝 The Script

If you prefer to create the file manually, copy the code below into a new text file and save it as Locker.bat.

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 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 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_HERE 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

🧠 How It Works (The Technical Part)

This script uses a built-in Windows feature called CLSID (Class Identifier).

1. Renaming: When you lock the folder, the script renames Locker to Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}.
2. System Trick: The UUID {21EC2020-3AEA-1069-A2DD-08002B30309D} corresponds to the Windows Control Panel.
3. Result: Windows Explorer sees this UUID and treats the folder as a shortcut to the Control Panel, effectively hiding the original contents and changing the icon.
4. Attributes: The attrib +h +s command sets the folder as Hidden and System, making it invisible to standard users.

❓ Troubleshooting

Forgot Password? Since this is a script, you can right-click the .bat file and choose "Edit" to see or change the password.

Folder Not Hiding? Ensure "Show hidden files" is disabled in your Windows Explorer View settings.
