    /// This method calculates the accumulated size of a directory on the volume in bytes.
    ///
    /// As there's no simple way to get this information from the file system it has to crawl the entire hierarchy,
    /// accumulating the overall sum on the way. The resulting value is roughly equivalent with the amount of bytes
    /// that would become available on the volume if the directory would be deleted.
    ///
    /// - note: There are a couple of oddities that are not taken into account (like symbolic links, meta data of
    /// directories, hard links, ...).
