Export multiple tracks to one gpx / kml / kmz file
I have got the same question like it is described here:
One of my folders contains some routes. I would like to export them into one gpx file, so I need to add in Google's "My Map" one new layer and import only one file. Importing multiple files in "My Map" is very time consuming. Therefore, the exported routes should all be in one single file.
Is it possible?
With best regards,
