How to use Google Earth KML files.

Get it here….
Second, find the KML file you want in the files section and “right-click”
on it. Select “Save target as…” from the popup menu.
Place the file someplace where you can find it later like your desktop

on your machine the KML file icon should look like this…
Minimize your browser and go to the place where you saved the KML
file and double click on it. Google Earth will open and fly to the
location the KML file describes.
