This is an Activity for the One Laptop Per Child (OLPC) project. It lets you import items from removeable devices like USB drives and SD cards using a familiar hierarchical view of files on these devices, as opposed to the flattened and IMHO misleading "Journal" view that the Sugar Journal gives to these devices. It also enables you to see how much disk space each Journal entry uses, generates thumbnails, and does other things to enhance your use of the Journal.
