wxFileName encapsulates a file name. This class serves two purposes: first, it
provides the functions to split the file names into components and to recombine
these components in the full file name which can then be passed to the OS file
-functions (and \helpref{wxWindows functions}{filefunctions} wrapping them).
+functions (and \helpref{wxWidgets functions}{filefunctions} wrapping them).
Second, it includes the functions for working with the files itself. Note that
to change the file data you should use \helpref{wxFile}{wxfile} class instead.
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 );

wxFileName currently supports the file names in the Unix, DOS/Windows, Mac OS
and VMS formats. Although these formats are quite different, wxFileName tries
File names can be case-sensitive or not, the function\rtfsp
\helpref{IsCaseSensitive}{wxfilenameiscasesensitive} allows to determine this.
-The rules for determining if the file name is absolute or relative also depends
-on the file name format and the only portable way to answer to this question is
-to use \helpref{IsAbsolute}{wxfilenameisabsolute} method. To ensure that the
-filename is absolute you may use \helpref{MakeAbsolute}{wxfilenamemakeabsolute}.
-There is also an inverse function
-\helpref{MakeRelativeTo}{wxfilenamemakerelativeto} which undoes what
-\helpref{Normalize(wxPATH\_NORM\_DOTS)}{wxfilenamenormalize} does.

+depend on the file name format and the only portable way to answer this
+question is to use \helpref{IsAbsolute}{wxfilenameisabsolute} or\rtfsp

+refers to the current working directory on drive X. Therefore, a wxFileName
