Ricardo I may not have explained myself very well.

In a normal path that has been created by anyone using GE you can click on the kml file that has been opened on the left and go edit. (if it is in a kmz you need to save it as a kml first). I think you can do this with the free version if you use one someone else has created.

You can then find the path in the file, select edit and then move any of the points in the path. The point are small placemarkers in the path for the coordinates. You have to zoom down pretty close to see the point markers.

With GEPath when you try to edit the path the message from the previous post appears and you can only edit one point and not any of those elsewhere in the path.

I hope this makes it clearer.
