Thanks for the suggestions.

This is the comment, from the Archive::Zip CPAN document's Overview section, which is not clear. Specifically, does this mean that files on disk which have NOT YET been written to an archive are merely pointed to when I perform a $tar->addfile(xxxxx)?

Archive members hold information about the individual members, but not (usually) the actual member data. When the zip is written to a (different) file, the member data is compressed or copied as needed. It is possible to make archive members whose data is held in a string in memory,...

I hope my "big data" client will test this for me. I will report back.
