Several third-party applications can lock folders with passwords. Some popular options include:

• VeraCrypt

Example with 7-Zip:

1. Download and install 7-Zip from the official website.
2. Right-click the folder you want to lock and select 7-Zip > Add to archive….
3. In the dialog box, set a password and choose AES-256 encryption.
4. Click OK to create a password-protected archive.

Method 3: Creating a Batch File

You can create a simple batch file to lock a folder with a password. Here’s how:

1. Open Notepad.
2. Copy and paste the following code:
   batch

   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 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

3. Replace YOUR_PASSWORD with your desired password.
4. Save the file as locker.bat (make sure to select “All Files” in the “Save as type” dropdown).
5. Double-click locker.bat to create a folder named Locker.
6. Move the files you want to lock into the Locker folder.
7. Double-click locker.bat again, and press Y to lock the folder.

Method 4: Using Hidden and System Attributes

You can manually set folder attributes to hide it:

1. Open Command Prompt.
2. Use the following command to hide the folder:
   batch

   attrib +h +s "C:\Path\To\Your\Folder"

3. To unhide the folder, use:
   batch

   attrib -h -s "C:\Path\To\Your\Folder"


Each method has its own level of security and convenience. Choose the one that best fits your needs.
