 wxFileName provides functions for working with the file attributes.
 

+When working with directory names (i.e. without filename and extension)
+make sure not to misuse the file name part of this class with the last
+directory. Instead initialize the wxFileName instance like this:
+
+\begin{verbatim}
+wxFileName dirname( wxT("C:\mydir"), wxEmptyString );
+MyMethod( dirname.GetPath() );
+\end{verbatim}
+
+The same can be done using the static method \helpref{wxFileName::DirName}{wxfilenamedirname}:
+
+\begin{verbatim}
+wxFileName dirname = wxFileName::DirName( wxT("C:\mydir") );
+MyMethod( dirname.GetPath() );
+\end{verbatim}
+
+Accordingly, methods dealing with directories or directory names
+like \helpref{IsDirReadable}{wxfilenameisdirreadable} use
+\helpref{GetPath}{wxfilenamegetpath} whereas methods dealing 
+with file names like \helpref{IsFileReadable}{wxfilenameisfilereadable}
+use \helpref{GetFullPath}{wxfilenamegetfullpath}.
+
+If it is not known wether a string contains a directory name or
+a complete file name (such as when interpreting user input) you need to use
+the static function \helpref{wxFileName::DirExists}{wxfilenamedirexists}
+(or its identical variants \helpref{wxDir::Exists}{wxdirexists} and
+\helpref{wxDirExists}{functionwxdirexists}) and construct the wxFileName
+instance accordingly. This will only work if the directory actually exists,
+of course:
+
+\begin{verbatim}
+wxString user_input;
+// get input from user
+
+wxFileName fname;
+if (wxDirExists(user_input))
+    fname.AssignDir( user_input );
+else
+    fname.Assign( user_input );
+\end{verbatim}
