Good morning, folks. I've used the search function and found several threads
that almost answer my question, but they're quite old and not exactly what I'm
concerned with.

I'm trying to backup a website that hosts podcasts.

Show info is located at www.foo.bar/show/#/date.

The corresponding MP3s are located at archive.foo.bar/episode.mp3

Previously (2012) I had painstakingly downloaded every episode at that point
by hand via Downthemall, so I have around 30GB of files I'd prefer not to
re-download.

However, I've noticed that even with the files in (what I assume to be) the
proper folder (archive.foo.bar) the old files get deleted and then
re-downloaded. I have tried various configs like "don't purge old files" and I
have Update Hack enabled. I've even tried "don't use cache" in my attempts at
troubleshooting.

Am I using this software in an incorrect manner, and that I should be
expecting re-downloads because WinHTTRack is grabbing the files it is designed
to, instead of what I want?
Is there a way to get this to work how I want, or should I go back to manually
using Downthemall?
Thanks for your advice, either way. I've used this software for other backups
and it worked perfectly, just this instance seems to be giving me a headache.
