Hi.
This text below, is from the file >RealFlight G4 Manual.pdf< it describes how you can import files. :
Import
The Import menu item allows you to utilize, or import, content created by other users.
There are three types of files that are associated with RealFlight G4; each will be
covered in the section that follows.
RealFlight Archive (RFX, G3X)-
RFX is the file extension that is used for all files exported from RealFlight G4.
This menu option allows you to import an RFX file. You will use this for all
files that you have downloaded. There is nothing special you need to know
about the file beforehand; the RFX importer handles all types of content,
including planes, color schemes, airports, PhotoFields, and recordings.
After choosing the Import menu item followed by the RealFlight Archive
(RFX, G3X), you will be presented with an Open file dialog. Use this dialog to
find the file that you want to import. Double-click the file or click the file and
click Open. The import process will start immediately and once it’s finished
you will see a message confirming its success.
This menu item also allows you to import G3X files used in RealFlight G3 and
G3.5.
