210             =head1 DESCRIPTION
211              
212             This module provides Windows-specific implementations for determining
213             common user directories. In normal usage this module will always be
214             used via L.
215              
216             Internally this module will use L::GetFolderPath to fetch the location
217             of your directories. As a result of this, in certain unusual situations
218             (usually found inside large organizations) the methods may return UNC paths
219             such as C<\\cifs.local\home$>.
220              
221             If your application runs on Windows and you want to have it work comprehensively
222             everywhere, you may need to implement your own handling for these paths as they
223             can cause strange behaviour.
224              
225             For example, stat calls to UNC paths may work but block for several seconds, but
226             opendir() may not be able to read any files (creating the appearance of an existing
227             but empty directory).
228              
229             To avoid complicating the problem any further, in the rare situation that a UNC path
230             is returned by C the usual -d validation checks will B be done.
231
