This will create a new folder,import the items into the folder created .Once you click the folder the folder get locked and disappeared. Here is the batch file program. Read the below steps carefully

5.  if NOT EXIST Secure goto MDLOCKER
6.  :CONFIRM
7.  echo Are you sure you want to lock the folder(Y/N)
8.  set/p “cho=>”

30.  goto end
31.  :MDLOCKER
32.  md Secure
33.  echo Secure created successfully
34.  goto End
35.  :End

• Copy this code and save it with  .bat  extension .
• Once you click the batch file you will see the folder named secure .
• You should import the files you need hide to this folder.
• You can also change the name of the folder in replacing all the occurrence of Secure with the name you want.
• Initially the password to open the folder Secure password.
• You can change the password in line 23 by replacing password with password you want. 

 Thank you.
