.swf file upload script files will not upload - upload

Question

Im trying to get this very basic script to upload .swf files to my server with no luck.
I get an invalid file error when i try to upload.
.jpg,gifs,pngs all upload fine.
I tried changing a few things putting swf where jpg is etc. but no joy.
Is it not possible to upload swf files in this way?
and help appreciated, many thanks.
