Hii, i want to ask. can we load file waypoint from other dekstop??. i mean, my friend email me the file waypoint but i cant to load in my mission planner that file?? have solution??

Did you tried load file from the plan tab. Your file should be “.waypoints” format

Which software was used to create the waypoint file?
Which software version are you using to upload the waypoints?

Is that an ArduPilot waypoint file?

It should be possible.
