Lock a folder without any software!!!!! in Windows XP

Hi friends,
U can lock any folder without any softwares. Using the codes given below u can redirect the folder to control panel, internet explorer etc., by renaming the files by pasting the code for example if u have a folder in d: which is named as "HELL" then rename it to Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}. thats all ur folder will redirect to control panel.

Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}
Internet Explorer.{FBF23B42-E3F0-101B-8488-00AA003E56F8}
Recycle Bin.{645FF040-5081-101B-9F08-00AA002F954E}
My Computer.{20D04FE0-3AEA-1069-A2D8-08002B30309D}
My Documents.{ECF03A32-103D-11d2-854D-006008059367}
Fonts.{BD84B380-8CA2-1069-AB1D-08000948F534}

to unlock the folder
Go to Start>RUN>CMD
If the folder is in d: then go to that drive
then type dir/x then the folder is shown as for example with control panel it shows as contro~1.{21
rename this folder to any name using command "ren control~1.{21 myfolder" without quote ok
that it all over..... U can lock and unlock the folder
