I am dual-booting windows 8 and Ubuntu 12.10. Now I have all my documents and media files in the windows partition/windows library. In windows, for example, in the documents library we can add a folder from other directories so we can view all those in one single place. So how can I view all those folders in windows partition under Ubuntu libraries?
