Abstract

See full text

Devices and methods are provided for generating difference files that include encoded differences between byte streams of original and new file versions. Generation of the difference files includes processing by components of an optimizing system and/or algorithm to identify replacement content in a first area of the new byte stream. The replacement content includes a group of bytes of the new byte stream identified as at least one of byte insertions and byte replacements in a corresponding operation array. The optimizing system identifies content similarities between the replacement content and at least one of the original byte stream and a second area of the new byte stream. The optimizing system generates information of the difference file by encoding information of the content similarities.
