making invisible folder

Sometimes we need to hide our data in a folder and we dont have folderlock software with us
Thats where exactly we require creating an invisible folder.So here is the basic steps

• Turn on Your Numlock key
• create a new Folder,and rename it.(You can also rename your existing folder)
• Type 255 from your num pad,while holding Alt Button.Not from ur alphabet pad.
• Press Enter.You will notice u have created a folder without a name
• Now right click-> properties->customize->Change icon button
• Scroll the icon and click on any empty area
• press ok->apply->ok

and you're done.The icon of the folder is invisible

in a simple way,we have created the folder w/o any name and just changed its icon to nothing
