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).

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,
+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 );

wxFileName currently supports the file names in the Unix, DOS/Windows, Mac OS
and VMS formats. Although these formats are quite different, wxFileName tries
-to treat them all in the sam generic way. It supposes that all file names

consist of the following parts: the volume (also known as drive under Windows
or device under VMS), the path which is a sequence of directory names separated
by the \helpref{path separators}{wxfilenamegetpathseparators} and the full
extension. All of the individual components of the file name may be empty and,
for example, the volume name is always empty under Unix, but if they are all
empty simultaneously, the filename object is considered to be in an invalid

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

+question is to use \helpref{IsAbsolute}{wxfilenameisabsolute} or\rtfsp
