/// If [newPath] identifies an existing directory, then the behavior is

/// if the existing directory is not empty. On POSIX systems, if [newPath]
/// identifies an existing empty directory then that directory is deleted
/// before this directory is renamed.
/// If newPath identifies an existing file the operation fails and a
