Araxis Merge 99 Professional is a two- and three-way file comparison/merging and folder synchronization application. It features side-by-side file diff, merging with in-place editing, directory hierarchy comparison/merging, and full printing support. It enables you to work with and compare different versions of the same text file. A color-coded, side-by-side comparison makes it easy to pinpoint similarities and differences between two files at a glance. This is a 30-day trial. A single-user license is $149.
