This information is very helpful. One last questions if you have time, so we understand that the viewer needs to figure out the file type, but once it does that, how does it render the file? How does the file rendering work?
I am writing a research article on the importance of universal viewers and how they can be used in the preservation of digital records (ie. computer files). Can you please tell me the technical basis of how the universal viewer works? How does it identify the various supported file formats and view them in the viewer? Any information would be very helpful, I am having a tough time finding information on how universal viewers actually work. Thank you
