SWF is a multipurpose multimedia format widely used on the web. It is also known by many other names (often conflated with the names of SWF players), such as Flash, Adobe Flash, Macromedia Flash, Shockwave Flash, and FutureSplash.
Fundamentally it is an animated vector graphics format, but it has many other features and is fully programmable. Among its common uses are web site user interfaces, video games and other applets, and video playback. The native programming language for SWF development is ActionScript.
