attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Locker
echo Folder Unlocked successfully
goto End
:FAIL

md Locker

goto End
:End

* Change the word "LOCKME" in above code with your password.
* Save it as batch file ( with extension .bat ) For eg. Locker.bat
* Now you will see a batch file. Double click it to create a folder locker ( A new folder named Locker would be formed at the same location )
* Thats it you have now created your own locker and that too without using any software !
* Brings all the files you want to hide in the locker folder.
* Double click the batch ( As created above ) file to lock the folder namely Locker

If you want to unlock your files, simple double click the batch file again and you would be prompted for password ( In DOS window ). Enter the password and enjoy access to the folder.
