Password Protect folders in Windows without any Software

1. Open Notepad.

2. Copy and paste the exact code given below:-

cls
@ECHO OFF
title techhub
if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK
if NOT EXIST MyFolder goto MDMyFolder
:CONFIRM
echo Are you sure to lock this 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 MyFolder "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 Your Secure Folder
set/p "pass=>"
if NOT %pass%== techhub goto FAIL 
attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" 
ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" MyFolder 
echo Folder Unlocked successfully 
goto End 
:FAIL 
echo Invalid password 
goto end 
:MDMyFolder
md MyFolder
echo MyFolder created successfully 
goto End 
:End

3. Click on the File Menu. Click on Save As.4. Select All Types in the Save As Type Drop Down menu. Save the file as anyname.bat or pankaj.bat.

After creating the file, double click on the Saved file. A new folder will be created. Enter your data in the folder. Again, double click on the batch file. Type Y and press Enter. The folder will be hidden from view.
To re-view your folder, double click on the saved batch file. 

Enter password as "techhub" without quotes and press Enter key. This is also the default password. Your folder will be visible again.
To change the default password, edit the part of the code given in blue and enter your own password.

The overall usability of this trick can be improved by deleting the batch file after hiding your folder and re-creating it when you wish to access your folder again.

Note: This works on Windows 10, Windows 8.1, Windows 8, windows 7, Windows XP and Vista. First try this on useless data to be sure and then only hide your personal data.
