It will be called with multiple sets, the sets will be pre-sorted for
you. The method should not open multiple connections, if that is needed
then it is simpler to fork multiple methods. All it needs to do is to
optimize it's connection to the host for the case of multiple files.

It checks only the date of the file in ../ to determine if it has changed
on the server. The size is never checked beacuse of decompression.
