The PATCH file format is a plain text representation of differences between files, originally created by Larry Wall for the Unix operating system and currently maintained by the Free Software Foundation. It is primarily utilized in software development for distributing source code updates and managing version control changes without transmitting entire files. As text-based data, these files are generally considered safe; however, since they can automate code modifications, users should verify content integrity before applying them to critical systems.
