XDBF files are used by the Xbox 360 as a generic database of sorts. It is used as the format for GPD (Gamer Profile Data) and SPA (Statistics, Presence and Achievements) files. SPA files are linked into an Xbox 360 executable during compilation and are used by the dashboard to generate the GPD files inside profiles and for Xbox LIVE information.
