Back up footprints by exporting them.
You can also open exported footprints files in other applications such as
Google Earth™ on your PC.
Select the footprints to export, and then tap
Footprints are exported as .kmz files. If you exported multiple footprints at one time, they are saved together in one .kmz file.
Tip: After exporting, tap
