The BSDIFF file format is a binary file format used mainly for software update processes and software patch delivery. Primarily, BSDIFF extension files work by comparing the old version of a software program with the new version, detecting the changes, and compressing them into a single BSDIFF file[1]. This strategy allows for compact software updates and patches, significantly reducing the size of downloads needed for software updates. Therefore, mostly, handling of BSDIFF files falls under the jurisdiction of software developers and system administrators.
Using BSDIFF Files in Software Development and Distribution
BSDIFF files are particularly useful in software development and distribution. They contain delta updates intended for software applications. These updates highlight the differences between old and new versions of the software. As a result, when an end user needs to update their software, instead of downloading the entire new version of the software, they just download the BSDIFF file that contains the changes[2].
Opening and Using BSDIFF Files with Patch Tools
To open and use BSDIFF files, you need specific tools capable of handling binary patch files. For example, the bsdiff tool is one such utility specifically designed for dealing with BSDIFF files[3]. This open-source utility comprises of two main components: bsdiff and bspatch. The former creates the BSDIFF files, while the latter applies these patches to binary files. Unfortunately, these command-line utilities may be technically challenging for average users, as they require a reasonable knowledge of command-line interfaces.
Other BSDIFF File Uses: Binary Differencing in Version Control Systems
Other than software updates, BSDIFF files have found use in version control systems. In such systems, differing versions of files must be kept track of in an efficient manner. With BSDIFF files, only the changes between different versions are stored, rather than complete copies of each version. This makes storage much more efficient, which is essential for large projects with many iterations[4].
BSDIFF File Important Information
While BSDIFF files offer many advantages, you should handle them with care. In particular, you should never open a BSDIFF file from an untrusted source, as they could contain harmful changes intended to damage your software or system[5]. As always, when dealing with any kind of file, it's important to have robust antivirus protections in place and to keep both your software and your system's operating system up to date.
