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,
+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 );

+\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
+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 whether the file name is absolute or relative also
+depend on the file name format and the only portable way to answer this
+question is to use \helpref{IsAbsolute}{wxfilenameisabsolute} or\rtfsp
+\helpref{IsRelative}{wxfilenameisrelative} method. Note that on Windows, "X:"
+refers to the current working directory on drive X. Therefore, a wxFileName
+instance constructed from for example "X:dir/file.ext" treats the portion
+beyond drive separator as being relative to that directory.
+
+To ensure that the filename is absolute, you may use\rtfsp
+\helpref{MakeAbsolute}{wxfilenamemakeabsolute}. 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}.
+
+
+\membersection{File name construction}\label{filenameconstruction}
+
+You can initialize a wxFileName instance using one of the following functions:
+
+\helpref{wxFileName constructors}{wxfilenamewxfilename}\\
+\helpref{Assign}{wxfilenameassign}\\
+\helpref{AssignCwd}{wxfilenameassigncwd}\\
+\helpref{AssignDir}{wxfilenameassigndir}\\
+\helpref{AssignHomeDir}{wxfilenameassignhomedir}\\
+\helpref{AssignHomeTempFileName}{wxfilenameassigntempfilename}\\
+\helpref{DirName}{wxfilenamedirname}\\
+\helpref{FileName}{wxfilenamefilename}\\
+\helpref{operator $=$}{wxfilenameoperatorassign}
+
+
+\membersection{File tests}\label{filetests}
+
+Before doing other tests, you should use \helpref{IsOk}{wxfilenameisok} to
+verify that the filename is well defined. If it is,\rtfsp
+\helpref{FileExists}{wxfilenamefileexists} can be used to test whether a file
+with such name exists and \helpref{DirExists}{wxfilenamedirexists} can be used
+to test for directory existence.
+
+File names should be compared using \helpref{SameAs}{wxfilenamesameas} method
+or \helpref{operator $==$}{wxfilenameoperatorequal}.
+
+For testing basic access modes, you can use:
+
+\helpref{IsDirWritable}{wxfilenameisdirwritable}\\
+\helpref{IsDirReadable}{wxfilenameisdirreadable}\\
+\helpref{IsFileWritable}{wxfilenameisfilewritable}\\
+\helpref{IsFileReadable}{wxfilenameisfilereadable}\\
+\helpref{IsFileExecutable}{wxfilenameisfileexecutable}
+
+
+\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{RemoveLastDir}{wxfilenameremovelastdir}
+
+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{ClearExt}{wxfilenameclearext}\\
+\helpref{SetEmptyExt}{wxfilenamesetemptyext}\\
+\helpref{SetName}{wxfilenamesetname}\\
+\helpref{SetVolume}{wxfilenamesetvolume}\\
+
+
+\membersection{Operations}\label{filenameoperations}
+
+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}
