// //////////////////////////////////////////////////////////////////////////
// Properties:
// NO Abstract class (does not have any objects)
// YES Derived from CObject
// NO Is a Cwnd.
// NO Two stage creation (constructor & Create())
// NO Has a message map
// NO Needs a resource (template)
// NO Persistent objects (saveable on disk)
// NO Uses exceptions
// //////////////////////////////////////////////////////////////////////////
// Desciption :
// This class encapsulates the directory specification on Windows NT
// supported file systems (FAT, VFAT, NTFS, HPFS)
// A directory consists of a drive specification, followed a subdirectory
// Remark:
// Directory specifications are always represented in upper case characters
// An implicit conversion is done when the supplied names are in lower case;
// All member functions starting with "Do" will physically change something
// on disk. Other functions only change the internal data.
// E.g. The normal destructor only destroys the internal representation,
// to actually remove a directory use DoRemove()
// Prerequisites (necessary conditions):
//
// Limited edition:
// In the not registered version (#define NOT_REGISTERED)
// a limited implementation of COXDirSpec is provided
// The function DoCopyDirectory() is not implemented
