Thanks to everyone for the help.

JS hit it. At least, I now know where the file is originating.

Checking SeeYou as he suggested shows the file is coming from SeeYou
Mobile running on the PDA. The GPS engine is reported as Volkslogger
which is correct.

Now, I just need to figure out why P-Strepla shows it has found the
Volkslogger, and has the correct file, but somehow downloads the
SeeYou file on the PDA to the SD Card.
