GetEffectivePermission method of the Win32_Directory class

The GetEffectivePermission WMI class method determines whether the user has all of the required permissions specified in the Permissions parameter for the Win32_Directory object, directory, and share where the directory entry file is located (if the file or directory are on a share).

This topic uses Managed Object Format (MOF) syntax. For more information about using this method, see Calling a Method.
