\description{

}

\details{
  For most file systems, the short form is the \sQuote{DOS} form with
  8+3 path components and no spaces, and this used to be guaranteed.
  But some file systems on recent versions of Windows do not have short
  path names when the long-name path will be returned instead.
}
\value{
  A character vector.  The path separator will be \code{\\}.  If a
  file path does not exist, the supplied path will be returned with slashes
  replaced by backslashes.
}
\note{
  This is only available on Windows.
