How do i open a .swf file?
Or how can i get it playing in my browser?
As it as a game that i downloaded.

You'll need to download either shockwave or flash player (maybe the plug in for the browser too, dunno, that all i know )

Just drag n drop the .swf file to your browser's window.
As long as you have Adobe Flash Player installed, the flash file should play fine....

File->Open (File) (ff)
Or
Right Click the file->Open With->[Browser]
