There are so many software’s available in markets for encrypting your personal data. In windows we can create a locker without using any locking software’s.This simple locker is compatible with windows 7,Vista,XP,98. Here is the trick !

• Step 1: Copy the code given below to a text editor (e.g. notepad )

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

• Step 2 : Replace lockername in the code with name of the folder you want to create
• Step 3 : Replace mypassword in the code with password you want to put to the locker(use passwords without space or special characters)
• Step 4: Save the file as key.bat into the location where you want to create the locker (save directly to a drive and avoid saving inside other folders)

You are done :-)

Accessing You Locker

• Clicking on the file key will create a folder with your locker name if it does not exist.
• Put your personal data inside the folder and click on the file key to lock it. Now your locker will be hidden and inaccessible to other users
• To unlock your locker again click on the file key and enter your password

This is a simple locker and does not provide security against people with good knowledge in programming.
