From Nabocorp Softwares:
My Folders allows you to define a keyboard shortcut that you can activate at any time, whatever the application you are running is. Press the key combination and a menu with shortcuts to predefined folders (customizable of course).
Choose one of the folders and an Explorer window browsing the selected folder will instantly appear. Of course the folders that appear in this menu are entirely customizable: you can even individually customize the icon that will appear next to each folder by selecting the icon of your choice. The keyboard shortcut is also fully customizable. This version is the first release on CNET Download.com.
