You can do additional 2 steps to effectively hide your data
Step 1:
First hide the "private" folder and then move "locker.bat" file to any other location
So that no one else but you can find the private folder even if they know your password
And move "locker.bat" back to the actual location of your folder to access your folder by entering the password
Step 2:
Encrypt the "private" folder and deny all the permissions to system and user in the security tab
This will prevent any file to be found using the search option
