OziExplorer Waypoint Format - Another CSV format file. Tested against OziExplorer v 3.90.3a / Shareware. Contributed by Alex Mottram
Write all tracks into one file.
In normal case GPSBabel creates for each track a separate file (track.plt, track-1.plt, ...). With this option all tracks will be written into one file. A '1' in the third field of the trackpoint record signals the beginning of a new track.
