Araxis Merge is very good. It compares folders, sub folders and files, and highlights the differences in the HTML. It also produces reports. It is easy to use, but not free. ________________________________ From: austechwriter-bounce@xxxxxxxxxxxxx [mailto:austechwriter-bounce@xxxxxxxxxxxxx] On Behalf Of Janet Taylor Sent: Monday, 8 September 2008 4:27 PM To: austechwriter@xxxxxxxxxxxxx Subject: atw: Software to compare htm files? 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
