Is it only with the <trk> tags, or is the normal gpx header section
around that?

Use gpsbabel, this most likely will do the job.
In gpsbabel, you can have many input files and one output. With the
program there is gpsbabelgui - a graphical MS Windows frontend.

Hi,

Thanks for the link, I had not searched for "AWK" in many years and found
little back then.

Perl does so much, AWK is just a tiny part of it.

There is / was an AWK to Perl translator that produced (To my eyes) a Perl
program that was unreadable but ran.

TAWK looks great, I have downloaded it!

But the comment about GPSBable is the one to follow and use for this task.

I have not needed to upgrade GPSBable to the latest but I now will even
though the "GPX" file problems appear to be solved in the latest Topo 9
software for my PN-60 GPS (Which replaced a PN-20). Tracks are now saved in
the "GPX" format.

I really should look into both tawk and Perl, since I was once (a long
time ago) conversant with awk, and Perl is one of the cool & powerful
languages, but I am trying to learn Android programming from some not
very good books, so I hesitate to start on a new language any time soon
:-)

It is good to get back on topic...

Thanks, everyone! I have GPSBable installed. Just didn't think
of checking it for this particular task.
