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.

-\membersection{File name format}

+\membersection{File name format}\label{filenameformat}
wxFileName currently supports the file names in the Unix, DOS/Windows, Mac OS
and VMS formats. Although these formats are quite different, wxFileName tries
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
+There is also an inverse function
\helpref{MakeRelativeTo}{wxfilenamemakerelativeto} which undoes what
\helpref{Normalize(wxPATH\_NORM\_DOTS)}{wxfilenamenormalize} does.

+\membersection{File tests}\label{filetests}
Before doing the other tests you should use \helpref{IsOk}{wxfilenameisok} to
verify that the filename is well defined. If it is,
File names should be compared using \helpref{SameAs}{wxfilenamesameas} method
or \helpref{$==$}{wxfilenameoperatorequal}.
-\membersection{File name components}
-These functions allow to examine and modify the directories of the path:
+\membersection{File name components}\label{filenamecomponents}
+
+These functions allow to examine and modify the individual directories of the
+path:
\helpref{AppendDir}{wxfilenameappenddir}\\
\helpref{InsertDir}{wxfilenameinsertdir}\\
\helpref{GetDirCount}{wxfilenamegetdircount}
\helpref{PrependDir}{wxfilenameprependdir}\\
-\helpref{RemoveDir}{wxfilenameremovedir}
+\helpref{RemoveDir}{wxfilenameremovedir}\\
+\helpref{RemoveLastDir}{wxfilenameremovelastdir}
To change the components of the file name individually you can use the
following functions:
\helpref{HasName}{wxfilenamehasname}\\
\helpref{HasVolume}{wxfilenamehasvolume}\\
\helpref{SetExt}{wxfilenamesetext}\\
+\helpref{ClearExt}{wxfilenameclearext}\\

\helpref{SetVolume}{wxfilenamesetvolume}\\

These methods allow to work with the file creation, access and modification
times. Note that not all filesystems under all platforms implement these times
