One warning.  I run a Fidonet BBS, which is connected to our campus Ethernet
system.  (This is handy, as the files are then available equally well to all
the campus microcomputers on the net, as well as all Vaxes on campus, and
in the future perhaps by FTP).

I was doing my backups using PKZIP to pack the files onto a network drive,
then I submitted a batch job that would put that file out onto tape from the 
VMS side.

Some of my PC directories have hundreds of files (message files for the Amiga 
echomail area for instance).  In total I had thousands of files on the hard
disk.  PKZIP gagged on this, saying something about attempting to put too 
many files into the archive.

I ended up using ZOO instead, which appears not to have this problem.  I still
use PKZIP for my own computer (which has fewer files) as PKZIP  with the -es
option is faster at creating the archives than ZOO is with no compression!
