Whats SWF?
SWF (acronym of “Shockwave Flash”, pronounced swiff) is a partially open file format for multimedia and especially vector graphics developed by FutureWave Software, and now controlled by Adobe. Intended to be small enough for publication on the web, SWF files can contain animations or applets of varying degrees of interactivity and function. SWF is also sometimes used for creating animated display graphics and menus for DVD movies, and television commercials. SWF is currently the dominant format for displaying animated vector graphics on the web, far exceeding the W3C open standard SVG, which has met with problems over competing implementations.
