A small web format (commonly abbreviated to 'SWF' and its plural form SWFs), is a flash file used for multimedia, vector graphics and ActionScript. The file format belongs to Adobe, currently being used in their program Adobe Flash.
SWF used to stand for ShockWave Flash file, however this meaning was eliminated and it was changed to small web format to avoid confusion.
An SWF, most simply, is a macromedia file. But it holds a deeper meaning to us Club Penguin players, of course. The reason for this is because without SWF files, the game would cease to exist, because Club Penguin was built out of, and runs with flash.
