Right, but the only way it can extract the last file ofthetar archive is
to expand the entire arcive (in order to determine the bytes at the end
of the archive).  .zip looks in the directory for the file, reads the
bytes representing the compressed file (and only that file), and uses
them to expand the file to its original version.
