Step 3
Save the "Text Document.txt" as "locker.bat"

Step 4

This is how it looks like after save.

Once you double click on that "locker.bat" file there will open folder name "Private" as shown below.

Then double click on that "locker.bat" file again. Then It will shows you a message as below

Press "Y" for hide the folder.

Step 5

In order to retrieve the Private folder again , all you have to do is double click on "locker.bat" file and enter the password that you assigned earlier.

That's it. Enjoy
