What am I doing wrong?

I have downloaded the quantum storage device,parachute,and pokeball.I extracted each of them to my addons.None of them are working.What did I do wrong.Where are they supposed to be located at?

If you unrar / unzip the file, you see this sometimes:
<foldername>/addons/<files>
<foldername>/scripts/<files>
If there are more folders, you need to place them in the good places, so scripts to scripts, addons to addons.
