\section{\class{wxFileName}}\label{wxfilename}
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}
wxFileName currently supports the file names in the Unix, DOS/Windows, Mac OS
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.
\helpref{IsRelative}{wxfilenameisrelative}
+
\membersection{File name construction}
TODO.
+
\membersection{File tests}
Before doing the other tests you should use \helpref{IsOk}{wxfilenameisok} to
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{SetName}{wxfilenamesetname}\\
\helpref{SetVolume}{wxfilenamesetvolume}\\
+
\membersection{Operations}
These methods allow to work with the file creation, access and modification
