of the path:

@li HasExt()
@li HasName()

@li DirName()
@li FileName()
wxFileName currently supports the file names in the Unix, DOS/Windows, Mac OS
and VMS formats (Mac OS no longer being maintained as OS X uses the Unix notation).
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
@ref getpathseparators() "path separators"
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 IsOk() returns @false for it.
File names can be case-sensitive or not, the function IsCaseSensitive() 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 IsAbsolute() or IsRelative() 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 MakeAbsolute(). There is also an inverse function
MakeRelativeTo() which undoes what Normalize(wxPATH_NORM_DOTS) does.
Other functions returning information about the file format provided by this
class are GetVolumeSeparator(), IsPathSeparator().
Please note that many wxFileName methods accept the path format argument
which is by @c wxPATH_NATIVE by default meaning to use the path format
native for the current platform.
The path format affects the operation of wxFileName functions in several ways:
first and foremost, it defines the path separator character to use, but it
also affects other things such as whether the path has the drive part or not.
See wxPathFormat for more info.
Before doing other tests, you should use IsOk() to verify that the filename
is well defined. If it is, FileExists() can be used to test whether a file
with such name exists and DirExists() can be used to test for directory existence.
File names should be compared using the SameAs() method or operator=(). For testing
basic access modes, you can use:
@li IsDirWritable()
@li IsDirReadable()
@li IsFileWritable()
@li IsFileReadable()
@li IsFileExecutable()
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.

@section filename_format 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 path separators 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 wxFileName::IsOk() returns false for it.
File names can be case-sensitive or not, the function wxFileName::IsCaseSensitive()
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 wxFileName::IsAbsolute() or wxFileName::IsRelative()
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 wxFileName::MakeAbsolute().
There is also an inverse function wxFileName::MakeRelativeTo() which undoes
what wxFileName::Normalize(wxPATH_NORM_DOTS) does.
Other functions returning information about the file format provided by this
class are wxFileName::GetVolumeSeparator(), wxFileName::IsPathSeparator().
@section filename_construction File name construction
You can initialize a wxFileName instance using one of the following functions:

@li wxFileName::AssignDir()
@li wxFileName::AssignHomeDir()
@li wxFileName::DirName()
@li wxFileName::FileName()
@li wxFileName::operator=()
@section filename_tests File name tests
Before doing other tests, you should use wxFileName::IsOk() to verify that
the filename is well defined. If it is, FileExists() can be used to test whether
a file with such name exists and wxFileName::DirExists() can be used to test
for directory existence.
File names should be compared using the wxFileName::SameAs() method or
wxFileName::operator==(). For testing basic access modes, you can use:
@li wxFileName::IsDirWritable()
@li wxFileName::IsDirReadable()
@li wxFileName::IsFileWritable()
@li wxFileName::IsFileReadable()
@li wxFileName::IsFileExecutable()
