Lock File(s) on Windows Without Using Any Software


How many times have you wished of a software using which you can hide or lock files,  restricting its access to other unwanted users. Although there are various software available in market using which you can easily lock/hide files but, i personally dont trust them because most of them are bloatware or spyware.
In this post i am going to share a simple yet powerful way of locking and hiding important files using a the following method. Follow the instructions to make you own Locker ( Without any software !! ) :
  • Open notepad.
  • Copy the following code in notepad file :





    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 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-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






  • Change the “YOUR PASSWORD HERE” with your password.
  • Save it as batch file ( with extension .bat ) For eg. Locker.bat
  • Now you will see a batch file. Double click it to create a folder locker ( A new folder named Locker would be formed at the same location )
  • Thats it you have now created your own locker and that too without using any software !
  • Brings all the files you want to hide in the locker folder.
  • Double click the batch ( As created above ) file to lock the folder namely Locker.


If you want to unlock your files, simple double click the batch file again and you would be prompted for password ( In DOS window ). Enter the password and enjoy access to the folder.
