General explanation how xdelta works.
General explanation how xdelta works.

Xdelta is utility which is used to generate file of differences between two binary files. This essentially means, only modifications made between two binary files are saved as an file, this file is then easily shared to another user which can use it to generate modified file out from original file. This is especially useful if original file contains copyrighted material (e.g. game executable, rom) or if original files filesize is huge. In the example is used regular windows executable, .exe, but it can be used with any kind of binary file.

General use

For more options, use xdelta -h.
