Why would that be? It's been possible to append to an existing zip since 
the early 90s.

And even if MS Office was the exception, most people in a corporate 
environment do not use anything else that stores files on a networked drive.

[Depressing Story Bro]
One of my wife's coworkers: "I wish I could group my files logically 
instead of having them all in the same place."
Other coworker: "Oh, it's easy.  All you have to do is start Word, and 
click on File / Open...  From there there's an icon that allows you to 
create folders."
My wife: "There has to be an easier way..."
Coworker #1: "Yeah, why don't you call your husband... He works in IT, 
he should know"

Because on Netware servers, "deleted" is just another attribute for the 
file starting at sector XYZ.

So if the application deletes the existing file before recreating a new 
one, the server will have two copies of the file on disk, with one that 
has the deleted attribute.

So you could easily revert to earlier versions of the file by using the 
SALVAGE command.

(And yes, server-based backup software are smart enough to back up the 
deleted versions as well, if you asked them, just as they could backup 
compressed files without decompressing them)
