What is a DIFF file?

DIFF files mostly belong to Git. A *.diff file is a plain text document that shows the differences between two versions of a file. It lists the lines that have been added, removed, or changed, and is used to record modifications between file versions.
This format is frequently used in version control environments. For example, when using Git or tools from GNU Diffutils, a diff file is generated to capture changes in source code or text documents.
Usage Details:

File Comparison: It provides a side-by-side look at original and updated file content.

Applying Patches: The file can be used with patch utilities to update files automatically.

Structured Output: The format uses markers such as '+' for additions and '-' for removals, along with context lines.

FilExt.com note: To view a *.diff file, open it with any basic or advanced text editor like Notepad, Notepad++, or VSCode. This lets you inspect the exact modifications recorded in the file.
