${PAN_HOME}/ (which defaults to ~/.pan2, if the variable hasn't been set
in the environment). There will be one for each configured server, named
newsrc-1, newsrc-2, etc, by default.
If you have >1 server configured, servers.xml holds the server
configuration, including the correspondence between server and newsrc
file. If you wish, you can therefore rename the newsrc files to
something more descriptive (I have gmane.newsrc for instance, for gmane's
newsrc file) and set the entry in servers.xml accordingly (with pan shut
down, of course).
You can indeed delete the files (with pan closed, naturally) and pan
should regenerate them, but they track a number of things, including (I
think) the lists of groups for that server and which ones you had
subscribed, so if you delete it, you'll need to redownload the group list
and resubscribe.
Looking, there's also the newsgroups.xov file. You may need to delete or
edit this one as well. While the newsrc files track read vs. unread, the
xov file tracks global group totals and per-server high-water-mark -- the
highest xref number seen for the group, per server. At least, that's
what a quick peek inside seems to reveal.
As I mentioned, the files in the groups subdir mainly store threading and
display information (caching the most frequently used author names, for
instance, so pan can refer to them with a shorter index number rather
than the full author name for each one, thereby saving memory). This
information can be rebuilt if necessary, altho pan may take rather longer
to start if like me you've a rather larger cache and don't expire your
text groups, thus accumulating quite a database worth of messages that
pan will have to rethread if you delete its threading info as held in the
files in the groups subdir.
