    I wonder if we should use one of the many platform-independent path representations? We have the original Java `File`, the new Java `Path`, the Hadoop HDFS `Path`... If we use strings for paths, we run into the very problems that those packages are designed to address.
    
    For example, do the above handle the "D:" directory suffix on Windows? Resolving "." and ".." in paths? The "~" indicator of use home folder? These all vary across platforms.
