Not that I know of but if you right click on a folder you should be able to change the security settings to prevent users from accessing it (assuming XP or 2000+ with NTFS parts)

Use CACLS from the command line

Start -> Run
Hold down the Windows key + R
Start -> All Programs -> Accessories -> Command Prompt
and type "cmd" without quotes and press enter

Type the following:

cacls "Type the Path in here, example: C:\Documents and Settings\Admin" /E /R (Enter the Username Here Without Parenthesis)

Remember to keep the quotes in the path name.


cacls "C:\Documents and Settings" /E /R Admin

Hope this helps

its working great! although it is not in the registry but who cares its what i need.

*Now how can I limit the access only to one person for example the administrator?

*one thing why users who do not have access to the files can still change the permission if they type:
cacls "C:\Documents and Settings" /E /P Admin:F ?

Why use the command prompt, it is much easier if you use the GUI.

What OS do you have?

Win XP Home or MC
Log in with the user you want to beable to access the folder
Navigate to the folder in my computer
Right click and go to properties
Go to the sharing tab
Click the box next to 'Make this file private'

This will set it so that only the currently logged in user can access the folder

Win 2000 or XP Pro
Log in with the admin account
Navigate to the folder in my computer
Right click and go to properties
Go to the Securirt tab
You can add or remove users and groups from the list
     Users and groups on the list can be granted or denied permissions
     A deny will always trump an allow (Bob is a member of Finance group, Finance group has deny full control on c:\test, bob has allow full control on the folder; AS A RESULT BOB WILL HAVE DENY FULL CONTROL BECAUSE OF THE GROUP)

NOTE: You may need to disable inharintence to change permissions.  Do this by;
     WIN 2000: Uncheck the inharitance box under security Tab
     WIN XP PRO: I beleive you need to go to the advanced settings under security tab

Command prompt will let you edit (instead of replacing) using the /e switch.  You will need to take ownership of a file/folder to prevent others from changing it directly, however they can take ownership back if they are members of the administrators group.  Make sure that the other users are not members of the adminstrator group on the local computer.
