Run the exe. It will offer you some rectangle combinations like templates, either use them or ignore them and create your own places.
If you choose one of the templates you can copy and paste files and folders into the places.
If you want to create your own places, right click the tray icon and choose 'Places settings'. Use the + sign and browse to the file or folder you want.
(Folders with lots sub folders and files will take a while to appear and explorer.exe may even crash)
