Quicktime Viewer . This is a windows version of the quicktime movie viewer from Apple. The viewer will let you look at any PDF files. The viewer is now freely distributable. This is a very efficient way to produce and distribute more complex documents.
Replica Replica is another electronic document format.
You may download the viewer and install it as a helper application. I originally selected this format because the viewer was freely distributable. This is a windows compression utility. This is a very simple application that works through the Windows Notepad. I recommend looking at this one if you are selecting an editor to use.
