How to import the leap motion demo pack?

So i already installed UE4 from source, the leap motion plugin is working, i am trying to use the assets from the demo pack found here https://developer.leapmotion.com/gallery/unreal-4-7-demo-pack

I cannot get this to work. whenever i try to import them it just keeps going into the folders and says that theyre empty(which they are not). whenever i try to just move them to the content folder in the project root, i get two folders which do not have the assets in them. whenever i try to just drag them into the content browser, the window just fills up with errors that it couldnt import them. What am i doing wrong? how do i get these assets to work in unreal

So i figured it out, you need to manually move the files over to the content folder of your project, you cant just drag and drop them into the editor or import them.
