"ExtraFile is conceptual software art but with a practical usage.
Its main intention is to wiggle the static system of image file formats.
[It] all started with the idea of inventing a new image file format, a format
as a piece of art. Far away from the mainstream and commercial standards.
Just to express the feeling of using and saving data in a new, fictitious
or artificial way." -extrafile
