PathDiscovery:="C:\Documents and Settings\All Users"), _
FileIOPermissionAttribute(SecurityAction.PermitOnly, _
Append:="C:\Documents and Settings\All Users\Application Data"), _
FileIOPermissionAttribute(SecurityAction.PermitOnly, _
    Write:="C:\Documents and Settings\All Users\Application Data\Microsoft"), _
FileIOPermissionAttribute(SecurityAction.PermitOnly, _
    All:="C:\Documents and Settings\All Users\Application Data\Microsoft\Network")> _

Remarks

Path discovery controls access to the information in the path itself. This helps protect sensitive information in the path, such as user names, as well as information about the directory structure revealed in the path. This value does not grant access to files or folders represented by the path.

Note

For performance reasons, PathDiscovery should be granted only to directories, not to files. For example, PathDiscovery permission should be granted to paths such as C:\test and C:\test\, not to files such as C:\test\example.txt.

This property sets access for a single file or directory. Use additional attributes to specify additional files and directories.
