In its interface, it allow you to compare your files side by side and each difference is colored or highlighted according to the criterion of customization that you have configured.... (underlined, in bold, different font, etc.). This tool can compare as many files as you wish, to recognize uppercase and lowercase letters in your text, spaces, how to open the file (text or value), and more. By default, Notepad is the publisher of the program but this does not prevent you from using your own tool. It should be noted that the speed of loading and the comparison depends on the number of files or lines in your text.
