Try it with backslashes. I don't think we want an empty string. :)

In any case, the equivalent of File.basename is PathStripPath(), though 
you'll need to mix it with PathRemoveExtension() if there's an extension 
provided. The equivalent of File.dirname is PathRemoveFileSpec(). Note 
that you'll need to use backslashes for those functions to work.

To detect if a path is a root path use PathIsRoot(). This will return 
true for "C:\\" or "\\server\\share" or even just "\\server".
