ExamDiff Pro is a Windows tool for visual text and binary file and folder. It features a double-pane view that allows for side-by-side comparisons, with color-coded lines indicating whether each line is added, deleted, or changed.

For folder comparisons, just double-click a file to jump to a side-by-side file comparison. You can easily edit and synchronize files either using the built-in editor, or an external text editor of your choice.
