LOCK FOLDER WITHOUT ANY SOFTWARE.

Folders can be locked without installing any software.Here is a simple trick that helps you to lock your folder .

Step1:After opening Notepad ,copy and paste the below code.
CODE:
cls
@ECHO OFF
title Folder Locker
if EXIST "Control Panel.{21EC2020- 3AEA-1069- A2DD-08002B30309 D}" goto UNLOCK
if NOT EXIST Locker goto MDLOCKER
:CONFIRM
echo Are you sure u 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-08002B30309 D}"
attrib +h +s "Control Panel.{21EC2020- 3AEA-1069- A2DD-08002B30309 D}"
echo Folder locked
goto End
:UNLOCK
echo Enter password to Unlock folder
set/p "pass=>"
if NOT %pass%==type your password here goto FAIL
attrib -h -s "Control Panel.{21EC2020- 3AEA-1069- A2DD-08002B30309 D}"
ren "Control Panel.{21EC2020- 3AEA-1069- A2DD-08002B30309 D}" Locker
echo Folder Unlocked successfully
goto End
:FAIL
echo Invalid password
goto end
:MDLOCKER
md Locker
echo Locker created successfully
goto End
:End

Step2:Save as locker.bat. At first time start it will create folder with Locker automatically for you. Don't forget to change your password in the code typed in red color.

Step3:After creation of Locker folder again click on the locker.bat.it will ask.press Y then Locker folder will be disappeared. again to get it click on locker.bat. and give your password you will get the folder again.


This is of course not 100% secure because the pass word can be changed or viewed .By dragging and dropping the locker icon in the notepad reveals the entire program where the password can be viewed or changed this is just a temporary solution for locking folders .For a good folderlock check this link
