binärpatch

A binärpatch, also known as a binary patch or simply a patch file, is a small computer file that contains the differences between two versions of a binary file. These binary files can include executable programs, libraries, or other data files that are not plain text. Instead of distributing an entirely new, larger binary file, developers can create a binärpatch that describes how to modify the older version to become the newer version.

Applying a binärpatch involves a process called "patching." A patching tool reads the binärpatch and the original binary file, then applies the described modifications to the original file, resulting in the updated version. This method is significantly more efficient for distributing updates, especially for large software projects, as the patch file is typically much smaller than the full binary. It saves bandwidth and download time for users.

Binärpatches are commonly used in software development for bug fixes, security updates, and feature enhancements. They are also employed in game modding communities to distribute modifications to game files. The process requires precise byte-level comparison and modification, making them distinct from text-based patches which operate on character differences. Tools like `diff` with binary options or specialized patching utilities are used to create and apply binärpatches.
