DSB is the extension given to files associated with a tool called WonderShare DVD Slideshow Builder. Most often, this program is used to create presentations and videos using photos. DSB files are used to store information on how the final created presentation should look like (transitions, effects, duration). This file does not contain audio or video data, but only stores information about their location. DSB files are based on the XML format.

WonderShare DVD Slideshow Builder is a free alternative to Windows Movie Maker.
