So they plan on screwing with the zip format? That just seems silly. Well, as long as they don’t mess with tar or gzip I think I’ll be ok. Right now I don’t use zip very often. On occasion I have to send files to novice Windows users, and in such a case, I choose zip. If I’m sending something to someone using the old Mac OS (pre OS X) I’ll usually stuffit and then binhex it. For Mac OS X users, you can create a disk image (dmg) file, and you can always gzip that if you want to, but for the majority of things I do, the old fashioned tarball suits me just fine. tar and gzip, can’t live without them…
