How do I import OpenAir format

[kabong.steve]

I am unable to work out how to import openair format airspaces.

the downloads from openair do not have a file extension.

But FiF doesn't see any files in the folder except for KML files, so it doesn't seem to matter what i name the openair file (.txt, .openair, or nothing) it doesn't see it.

Please advise

thanks

solved.

by using the .txt filename extension.
