As a way of rejecting the limitations and bias of commercial image formats, Asendorf has created a suite of new image formats specifically tailored to the ideals and aesthetics of digital artists and glitch practices. 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. Getting the filename extension into the scope of the artwork itself. In simple terms: Creating an exclusivity. The freedom not to have to pay attention to the file size or the loading and saving times provides the option to implement artistically byte orders, odd quality behaviors and visual designed formats. ExtraFile is breaking the rules of commercial formats like JPG, PNG or TIFF. It is a pioneer art project in storing image data. The process and the resulting bytes, regardless of content, become the artwork itself.
