New KMB file format created by Maps.Me

[routeconverter]

I manage the source in GPX format files then export them in the format according to the applications or GPS that I use.

In the zip file, you will find
1. The original file (.gpx)
2. The file reworked for the old Maps.Me format (.kml)
3. The file converted by Maps.Me to the new format (.kmb)

The .kmb is unreadable binary stuff - and I couldn't google a tool that reads it.
   

 Even the support of Maps.me recommends to export .kml:

Isn't that an option for you?
