Lock your folder or drive using registry

[Porfirioo]

I am using Windows XP and I want to know the steps to lock my drives or folders using registry. I know there are many software but I don't want to use that. Using registry I want to make my folder or drive inaccessible to other users. Is there any setting in registry to lock the folder?

There are steps to lock your folder-
1 Consider a folder that you want to lock named XXXX in your D:\, whose path is D:\XXXX.
2 Open the Notepad and type the following-

 ren xxxx xxxx.{21EC2020-3AEA-1069-A2DD-08002B30309D}

3 Save the text file as loc.bat in the same drive.
4 Open another new notepad text file and type the following

ren xxxx.{21EC2020-3AEA-1069-A2DD-08002B30309D} xxxx

5 Save the text file as key.bat in the same drive.
6 Click the loc.bat to lock xxxx folder and it will transform into control panel icon which is inaccessible.
7 To unlock the folder click the key.bat file. Thus the folder will be unlocked and the contents are accessible.

To lock your drive follow this steps-
1 Click on Start > Run and type Regedit to open Registry editor
2 Naviagte HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Policies\Explorer
3 Create a new DWORD value NoViewOnDrive and set its value as
2^ (Alpha Number of Drive Letter-1) where Alpha number are simple counting of alphabets from A to Z as 1 – 26
For example: If you want to lock D:\, Alpha number of D is 4 so 2^ (4-1) = 8 (decimal value)
4 To unlock your drive just delete the key from the registry.
