Abstract
Methods and systems relating to a file distribution scheme in a computer network are disclosed that distributes files in an efficient manner that reduces, among other things, network traffic. In an embodiment of the invention, a method for updating a file is disclosed. In such a method, unique chunks in a first version of a digital file are identified. For a second version of the digital file, chunks that are the same as in the first version are identified. Recompilation information is generated and stored for these identified chunks. Also, for the second version of the digital file, chunks in the second version that are different from chunks in the first version are identified. Recompilation information is generated and stored for these identified chunks. With this information, the second version of the digital file is completely defined and can be efficiently stored.
