using pipe to export oracle on windows platform

Hi friends:
   We have to migrate a database on windows 2000 to Solaris, and to
another location. So we want to reduce the size of the dump file via
   As windows does not support pipe like we do in unix: mknod exp.pipe
p; gzip <exp.pipe >dmp.gz & and run exp. I tried cygwin. But seems
gzip simply do not do anything there. Anyone tried using pipe on
windows/cygwin? Or is there similar workaround?
