If you have Microsoft Visual Studio installed, then you can find there this utility:
"C:\Program Files\Microsoft Visual Studio\Common\Tools\WINDIFF.EXE"

>Working on some legacy stuff and have just finished reworking a PRG and see that there is another one that is very similar. Is there a clean way of comparing them to note the differences? I used Word, but it found every difference including where text positions were changed and Hex Workshop doesn't have enough flexibility in how the text is displayed or allowing a "result" document to be created. I want to generate a file that includes all the difference and then edit it. Thanks!
