A feature of Agent that I really like is the ability to preview an
archive before I download it completely. Until recently that was easy
to do: I just previewed the biggest file in the set. A new obfuscation
method has appeared that makes a dog's breakfast of the multiple parts
and I can't figure out which one to preview. It may not even be
possible for all I know. Has anyone figured this out?

The meaning of "obfuscation" is to make something obscure, unclear
and intelligble.

"Working As Designed"

Agent dates from those innocent childlike years before the era of
obfuscation techniques.

That era is gone and won't come back. And Agent can't do what it
wasn't designed to do. And given that it's more or less a dead
product, never will.

You'll have to change your way of operating in light of the way things
are now.

Oh I've moved on to SABnzbd for multipart binary downloading but it
doesn't have Agent's very useful Preview function. I've noticed that
when Agent downloads a complete set of these files, you get something
that looks like the following. (The numbers at the end of each line
are file sizes.)

08ffc6dd4af04287b981f4d0ee106177(1).mkv 0
08ffc6dd4af04287b981f4d0ee106177(10).mkv 0

08ffc6dd4af04287b981f4d0ee106177(15).mkv 15,204,352
08ffc6dd4af04287b981f4d0ee106177(16).mkv 0

08ffc6dd4af04287b981f4d0ee106177.mkv 0
08ffc6dd4af04287b981f4d0ee106177.par2 7,720
08ffc6dd4af04287b981f4d0ee106177.part01.rar 15,360,000

08ffc6dd4af04287b981f4d0ee106177.part11.rar 15,360,000
08ffc6dd4af04287b981f4d0ee106177.part12.rar 318,980

Notice that all the .mkv files except one are 0 bytes long. That is a
preview that's been packed into the set. If you play it you'll get
about two minutes of the start of the video. Every new-obfuscated set
that I've downloaded with Agent has one of these but it does not
always occur in the same position in the set.

I've told this to the SABnzbd community and hopefully someone will
figure out a way to extract the preview before downloading the
complete set...

I've found Agent these days to be most useful for reading/responding
to text-only postings; also for getting a rough idea of what's being
uploaded in the groups of interest to me. For the actual downloading
of anything but trivial binaries, more competent tools are called for.

That's obfuscation for you! Shitstorm of postings of crap to hide the
important items, I guess.

I don't normally bother with the unknown obfuscated material. I get
more than enough of what I'm looking for via other ways.

Admittely, I'm mainly browsing for things of possible interest rather
than doing determined searches for specific stuff, so there's possibly
less urgency about identification at all costs in my case.
