\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).

\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 sam generic way. It supposes that all file names
+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
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.
+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}.
+filename is absolute you may use \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} and\rtfsp
-\helpref{IsWild}{wxfilenameiswild}.

+
+This function splits a full file name into components: the volume (with the
+first version) path (including the volume in the second version), the base name
+and the extension. Any of the output parameters ({\it volume}, {\it path},
+{\it name} or {\it ext}) may be {\tt NULL} if you are not interested in the
+value of a particular component. Also, {\it fullpath} may be empty on entry.
+
+On return, {\it path} contains the file path (without the trailing separator),
+{\it name} contains the file name and {\it ext} contains the file extension
+without leading dot. All three of them may be empty if the corresponding
+component is. The old contents of the strings pointed to by these parameters
+will be overwritten in any case (if the pointers are not {\tt NULL}).
