So, before I get *too* far down this path, here's what I've come up with so far. Is this usable to you? AVI: AVI files can contain both audio and video. They can generally be played with media players such as Windows Media Player, WinAmp, or Mplayer. See <a href="http://en.wikipedia.org/wiki/.avi">here</a> for more information. CSS: CSS (Cascading Style Sheets) are generally used to make HTML pages look nice, and are not intended for direct viewing. Your web browser will find these files as referenced by the HTML files that use them. See <a href="http://en.wikipedia.org/wiki/Cascading_Style_Sheets">here</a> for more information. DVI: The output format of a typesetting system called TeX. Generally more common on Unix-like platforms. Can be viewed using xdvi or Evince. See <a href="http://en.wikipedia.org/wiki/DVI_file_format">here</a> for more information. EPS: Short for "Encapsulated PostScript", it can generally be viewed with any PostScript viewer. A free PostScript viewer is available at <a href="http://www.cs.wisc.edu/~ghost/doc/AFPL/index.htm. See <a href="http://en.wikipedia.org/wiki/Encapsulated_PostScript">here</a> for more information. GIF: An image format generally viewable by any web browser. See <a href="http://en.wikipedia.org/wiki/GIF">here</a> for more information. ISO: A logical copy of a CD-ROM or other optical media. Most CD/DVD authoring utilities can deal with ISO images. A free tool for mounting these images on a Windows machine as though they were inserted into a CD-ROM drive is available <a href="http://www.daemon-tools.cc/dtcc/download.php">here</a>. A tool for burning ISOs to a physical CD-R or CD-RW on Windows is available <a href="http://isorecorder.alexfeinman.com/isorecorder.htm">here</a>.
