File Extension Details
A DIFF file, also known as a patch file, is a plain text document that describes the differences between two versions of a file, typically source code. These files are generated by the 'diff' utility and are used extensively in software development to track changes, share updates, and apply fixes. The format typically follows a standardized syntax, such as the 'unified format,' which includes metadata about the files being compared and specific 'hunks' that show exactly which lines were added, removed, or modified. Because they only contain the changes rather than the entire file, DIFF files are highly efficient for version control systems like Git, SVN, and Mercurial. Developers use these files to perform code reviews, as they provide a clear, human-readable summary of modifications. They can be applied to an original source file using the 'patch' command-line tool to automatically update the code to the newer version. While they are primarily used for programming, any text-based data can be compared and stored in this format.
