Thingamahoochie Software's WinMerge allows you to sort a comparison of two folder structures by "Comparison result" and the items which have a "Text files are different" setting are the actual changes.

Other files which can appear in the list include those that will have "Text files are identical" and "Binary files are identical" at this column and also files that only exist in one spot but not the other. Also note that you may right-click on the name of file in the list and pick "Compare" to see what has changed in the "Text files are different" items. What is more, Copy Pathnames and Copy Filenames should be options one sees when one right-clicks amid a selection.
