Protecting your files or folders is important if your computer is used by others. There are lot more ways to protect your files/folders with a password but most of them requires installation of software. I am going to show you a simple and easy way to Lock Folder Using CMD.

STEP 1: Copy the following code to Notepad.

  cls
  @ECHO OFF
  title Folder Private
  if EXIST “Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}” goto UNLOCK
  if NOT EXIST Private 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 Private “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%== 1234 goto FAIL
  attrib -h -s “Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}”
  ren “Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}” Private
  echo Folder Unlocked successfully
  goto End
  :FAIL
  echo Invalid password
  goto end
  :MDLOCKER
  md Private
  echo Private created successfully
  goto End
  :End

STEP 2: In 23rd Line You can see the default password i.e., 1234 , so just change this to the password you want.
STEP 3: Save the file using any name you want with .BAT
STEP 4: Open that save file and enter the password and press Enter
STEP 5: After entering the password , it will create one folder named “Private”. So, copy any file or folders you want to hide and paste/move it to Private folder.
STEP 6: If you want to lock this folder, again open that BAT file. Type Y and then press enter, now your folder is locked or hidden whatever you can
