Questions about wpml file and requirements to upload a simple route to drone

[xenogit]

I am trying to create a route and upload it to a DJI M3E using DjiWaypointV3_UploadKmzFile (present in PSDK, but the waypoint documentation is in cloud API, hence why I posted the question here)

Saw from the documentation that the kmz file has the following formats.

.kmz

• res
• template.kml
• waylines.wpml

Questions:

1. Are all 3 file/folders required to be present in the .kmz file?
2. what is res (a folder? How to use it? What does it contain? Is it reference by template.kml or waylines.wpml?)
3. I notice that both template.kml and waylines.wpml contains similar sections.
   • Setup Mission Configuration
   • Setup A Folder for Waypoint Template
     3a) Do I require both template.kml and waylines.wpml in the .kmz file?
     3b) Do I need to generate both files with the same waypoint data since they contain the same sections?
