WinDiff is an application designed to enable users to compare two text files or two folders and view the differences between them. It is a part of the Windows Support Tools and can be used to identify differences between source code, web pages, configuration files, and other text-based documents. It is often used by developers and system administrators to identify changes between different code versions, as well as for debugging purposes. WinDiff presents the differences between the two files or folders in a graphical format, allowing users to easily identify and analyze the differences between them. It also provides a number of options for customizing the way the differences are displayed, including the ability to ignore certain sections of the files, or to filter the differences based on type.
