You've tried it all...opening the file through a media player, letting Internet Explorer choose how to open it, even changing the file type. However, if the file you have is a .swf, or Shockwave file, there's a simple solution. Follow these steps to open that tricky file!
How to Open a Shockwave File
First, you'll need to identify that the file you're dealing with is a Shockwave file. Look at the file extension, which is the last three letters of a file name, which always follow a period. A Shockwave file will end in .swf (for example, music.swf, or presentation.swf).
Next, download the Shockwave player from Adobe.
