+\membersection{File name format}
+
+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 same 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
+filename itself which, in turn, is composed from the base file name and the
+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
+state and \helpref{IsOk}{wxfilenameisok} returns {\tt FALSE} for it.
+
+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{Normalize}{wxfilenamenormalize}. There
+is also an inverse function \helpref{MakeRelativeTo}{wxfilenamemakerelativeto}
+which undoes what \helpref{Normalize(wxPATH\_NORM\_DOTS}{wxfilenamenormalize}
+does.
+
+Other functions returning information about the file format provided by this
+class are \helpref{GetVolumeSeparator}{wxfilenamegetvolumeseparator},\rtfsp
+\helpref{IsPathSeparator}{wxfilenameispathseparator}.
+
+\helpref{IsRelative}{wxfilenameisrelative}
+
+\membersection{File name construction}
+
+TODO.
+
+\membersection{File tests}
+
+Before doing the other tests you should use \helpref{IsOk}{wxfilenameisok} to
+verify that the filename is well defined. If it is,
+\helpref{FileExists}{wxfilenamefileexists} can be used to test if a file with
+such name exists and \helpref{DirExists}{wxfilenamedirexists} - if a directory
+with this name exists.
+
+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:
+
+\helpref{AppendDir}{wxfilenameappenddir}\\
+\helpref{InsertDir}{wxfilenameinsertdir}\\
+\helpref{GetDirCount}{wxfilenamegetdircount}
+\helpref{PrependDir}{wxfilenameprependdir}\\
+\helpref{RemoveDir}{wxfilenameremovedir}
+
+To change the components of the file name individually you can use the
+following functions:
+
+\helpref{GetExt}{wxfilenamegetext}\\
+\helpref{GetName}{wxfilenamegetname}\\
+\helpref{GetVolume}{wxfilenamegetvolume}\\
+\helpref{HasExt}{wxfilenamehasext}\\
+\helpref{HasName}{wxfilenamehasname}\\
+\helpref{HasVolume}{wxfilenamehasvolume}\\
+\helpref{SetExt}{wxfilenamesetext}\\
+\helpref{SetName}{wxfilenamesetname}\\
+\helpref{SetVolume}{wxfilenamesetvolume}\\
+
+\membersection{Operations}
+
+These methods allow to work with the file creation, access and modification
+times. Note that not all filesystems under all platforms implement these times
+in the same way. For example, the access time under Windows has a resolution of
+one day (so it is really the access date and not time). The access time may be
+updated when the file is executed or not depending on the platform.
+
+\helpref{GetModificationTime}{wxfilenamegetmodificationtime}\\
+\helpref{GetTimes}{wxfilenamegettimes}\\
+\helpref{SetTimes}{wxfilenamesettimes}\\
+\helpref{Touch}{wxfilenametouch}
+
+Other file system operations functions are:
+
+\helpref{Mkdir}{wxfilenamemkdir}\\
+\helpref{Rmdir}{wxfilenamermdir}
