How to put ex. ones picture folder, or other links, on the Metro UI s

How can I make easy access to folders, functions (other than those installed default) and app's directly from the Metro UI by making tiles there?

Just type whatever you want at the metro start screen, you don't need a box, just type and you'll automatically get a pane in the right with a search box and locations, you can choose whichever location you want. E.g. typing notepad will show up notepad.exe, right click on it and pin to the start menu. I'm not sure about folders yet, I was trying to pin Downloads folder but haven't succeeded yet.
