Directory structure in OS is the stable and scalable organization of files into a hierarchy of folders. It can be added to, but the fundamentals should don't change. These folders help computer users keep track of where everything on their PC is located.
Mac OS X has an open directory services architecture and built-in support for open standards, therefore Mac OS X desktops and servers can operate within a Macintosh NetInfo directory, a Microsoft Active Directory, or in an enterprise LDAP directory. With the usual provisos of naming conventions etc. (See links below)
