If you have the Shockwave Flash plug-in for Internet Explorer installed, you can see these files online at: https://elsmar.com/pdf_files/. All the .swf files are there (look by name). Using Explorer on both my PeeCee and my Mac, clicking on the file in my browser opens and allows you to ‘play’ the file. I don’t have Netscape for the PeeCee so I can’t check that, but on my Mac I cannot get the Netscape browser to play the file even though the plug-in is installed - so I doubt it will play with Netscape on the PeeCee.
NOTE: Microsoft’s Photo Editor does not ‘play well’ with animated gif files. It is not animated gif ‘aware’. You can see the first frame, but that’s it.
