Hi Janet ExamDiff (free) compares the content of one file to the contents in another, but their Pro version compares directories and files within directories, I believe. Details are here: http://www.prestosoft.com/ps.asp?page=edp_examdiffpro I haven't used the Pro version ($35), but ExamDiff (free; http://www.prestosoft.com/edp_examdiff.asp) is not bad.

Does anyone know of software (doesn't have to be free) that compares all the htm files in a folder with another version of the same files in another folder? I can find software that compares one htm page with another, but I have hundreds to compare at a time. The quality of the difference reporting is not as important as locating which htm files are different. Thanks
