John,
_is_ there something intrinsic to the format?
The specs to the format seem to indicate there is, and I found something to
manipulate it here :

And by the way, if you ever wondered what the rightclick - "properties" -
"summary" does: it saves, on an NTFS filesystem, the entered info into a
so-called "alternate data stream", which is attached/linked to your file
but, on XP, not visible when browsing files on (I've been biten by it once,
which is why I know. :-) ).
AFAIK those ADSes will be copied as long as you do it to another NTFS
filesystem (not a 100% sure about it though). No idea how a nowerdays
file-packer (7z ?) responds to it. It depends on which one you use and how
old it is I guess.
Personally I would not depend on those ADSes, but wanted to name them
regardless. - both as an option, but also as a warning :-)

Rudy Wieser
