I’m not sure what browser you use, but the way I open swf files is I start-up my broiwser (Firefox) and I drop the sfw file in an empty window (it doesn’t have to be empty) or I’d enter /home/<me>/ in the adres barnavigate to where the swf file is and just click on it, but flash for Firefox is ancient at version 11.2 while flash for Chromium is at version 20, so even tho I don’t use Chromium,I’d recommend installing Chromium and chromium-pepper-flash and chromium-ffmpeg the last two come from packman so just do
zypper in chromium chromium-pepper-flash chromium-ffmpeg
launch Chromium and drop the swf file in it’s window.
