Step # 1-Create a new text document

First of all create a new folder and you can rename it to whatever you want. Open the folder and create a text document.

Step # 2--Paste the code in the file

Once the text document is created, open the document and paste the code "*******". After pasting the code, to set the password, change the "password_goes_here" text to the password which you want to set.

Code:
Check the signs (more than)

cls
@ECHO OFF
title Folder Private
if EXIST "HTG Locker" goto UNLOCK
if NOT EXIST Private goto MDLOCKER
:CONFIRM
echo Are you sure you want to lock the folder(Y/N)
set/p "cho=(more than)"
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 "HTG Locker"
attrib +h +s "HTG Locker"
echo Folder locked
goto End
:UNLOCK
echo Enter password to unlock folder
set/p "pass=(more than)"
if NOT %pass%== PASSWORD_GOES_HERE goto FAIL
attrib -h -s "HTG Locker"
ren "HTG Locker" Private
echo Folder Unlocked successfully
goto End
:FAIL
echo Invalid password
goto end
:MDLOCKER
md Private
echo Private created successfully
goto End
:End

Step # 3 --Rename the text document

After you set the password to folder in Windows 7 save the file and close it. Rename the document to "locker.bat". Make sure it does not include ".txt".

Step # 4 --Enter password

After renaming the file, double click on it. A new folder named "private" will be created. Put your content in that folder and when you are done run the "locker.bat" file again. This time you will be asked if you want to lock the folder, press the "y" key and then hit "enter". The private folder will disappear and if you try to run the batch file again, the password protected folder will ask you for the password. To check whether it works, enter an incorrect password and see that it will not open the file. Once the correct password is entered the "private" folder will be accessible.
