+'''Description:''' Loading and saving in Blender is very fast and Blender is known to have excellent downward and upward compatibility. Ton Roosendaal demonstrated that in December 2008 by loading a 1.0 blend-file using Blender 2.48a.
 Saving complex scenes in Blender is done within seconds. Blender achieves this by saving data in memory to disk without any transformations or translations. Blender only adds file-block-headers to this data. A file-block-header contains clues on how to interpret the data. After the data, all internally Blender structures are stored. These structures will act as blue-prints when Blender loads the file. Blend-files can be different when stored on different hardware platforms or Blender releases. There is no effort taken to make blend-files binary the same. Blender creates the blend-files in this manner since release 1.0. Backward and upwards compatibility is not implemented when saving the file, this is done during loading.
-When Blender loads a blend-file, the DNA-structures are read first. Blender creates a catalog of these DNA-structures. Blender uses this catalog together with the data in the file, the internal Blender structures of the Blender release you're using and a lot of transformation and translation logic to implement the backward and upward compatibility. In the source code of blender there is actually logic which can transform and translate every structure used by a Blender release to the one of the release you're using. The more difference between releases the more logic is executed.]]

 In 1998, Ton founded a new company called Not a Number (NaN), to further market and develop Blender. NaN's business model involved providing commercial products and services  around Blender. In 2000 the company secured growth financing by several investment companies. Target was to create a free creation tool for interactive 3D (on-line) content, and commercial versions of the software for distribution and publishing.
