File Formats

A file format is generally marked by the letters after the last dot of the file name. There is not just one file format that puts any data into the format that has the best performance, features, editability, open specification, quality, and file size. There are good and bad aspects to each format. Often there are different formats that work better for text, graphics, video, sound, multimedia and page layout and many within each of those categories.

I spend a lot of time and effort thinking about and researching file formats to allow people to access my content without having to pay for or many times even download software. I also choose formats that are easy to view and support Windows, Mac OS X, and Linux at the least. I use many different formats to reach as many people as possible. Almost every part of my work is available in PDF format as an option.

I use open formats whenever possible. There is no single requirement that makes a format open. Open formats generally have a specification that is freely available to create import and export filters for appplications that view and edit in that format without any limitations like patents or monetary fees unless these are given away royalty free. The best way to see if a format is open is to see if there are open source viewers for that file format. I often use proprietary formats for audio and video because that is generally what people have installed. But every piece of content here is always available in at least one open format. My multimedia is always available in an open format like Ogg.
