Problem Installation Ardupilot

I have done the installation process as directed at
Up to apm connection stage to arduino IDE I did not find the contents of Sketchbook according to the image. There are only libraries, modules and Tools. For APMmover2, APMcopter and so on are not visible.
Can anyone provide a solution?

note: i am in a project making a boat survey.

I think you need download the specific version code,for example before arducopter3.2.1. Git clone will clone the latest code. The latest code cannot support arduino IDE.
Then add to the arduino libraries like this.
