Besides of a possibility of storing the whole tree of subdirectories (which can be fairly important, but can be achieved also with arc'ed shar or tar format) there is also a business of recovery. There is also the non trivial aspect, for everyday users of zoo or arc, that zoo is vastly faster, because it does not do two or more passes over the files to archive to determine which is the best compression method. Zoo uses one of the best compressions right away, betting that almost always is the optimal one, and is very much faster for this. Overall zoo is "arc with hindsight". -- Piercarlo "Peter" Grandi | ARPA: pcg%cs.aber.ac.uk@nsfnet-relay.ac.uk Dept of CS, UCW Aberystwyth | UUCP: ...!mcvax!ukc!aber-cs!pcg Penglais, Aberystwyth SY23 3BZ, UK | INET: pcg@cs.aber.ac.uk
