YaDT (Yet another Diff Tool) is a free file comparison tool that is used to compare two or three files to find out the differences and provides facility to merge those files. It is basically a command line tool that provides output in GUI (Graphic User Interface) window in which you can see differences highlighted in green color. You can enter the commands (along with paths) of two or three files such as text files, documents, or programming files to know the differences. It is quite useful for programmers, software developers etc. as they can easily identify the differences of source code files without going through manual process.

Moreover, YaDT tool provides facility to merge two files along with the preview facility. It is a useful tool but a bit different from visual file comparison software as it is command based tool. If you have a bit of knowledge about command prompt window usage, then you can easily work with this diff tool.
