xdelta is a command line program for delta encoding, which generates the difference between two files. This is similar to diff and patch, but it is targeted for binary files and does not generate huma

VCDIFF is a format and an algorithm for delta encoding, described in IETF's RFC 3284. The algorithm is based on Jon Bentley and Douglas McIlroy's paper "Data Compression Using Long Common Strings" wri

In computing, the utility diff is a data comparison tool that computes and displays the differences between the contents of files. Unlike edit distance notions used for other purposes, diff is line-or

In computing, file comparison is the calculation and display of the differences and similarities between data objects, typically text files such as source code. The methods, implementations, and resul

DiffEngineX compares two Excel spreadsheets and reports their differences. It compares cells (formulae, constants and calculated values), comments, defined ranges (names) and Visual Basic for Applicat

Diff-Text is a free software tool which finds the differences between two blocks of plain text, available on all operating systems. It takes the form of a collection of web-pages, each one with a slig

Delta encoding is a way of storing or transmitting data in the form of differences (deltas) between sequential data rather than complete files; more generally this is known as data differencing. Delta

In computer science and information theory, data differencing or differential compression is producing a technical description of the difference between two sets of data – a source and a target. Forma
