I use a product called FAR HTML which I use to compare changes I make to my help file. It psuedo- decompiles a chm file before comparing the individual html help topics. http://www.helpware.net/FAR/index.html <http://www.helpware.net/FAR/index.html> David. ________________________________ From: austechwriter-bounce@xxxxxxxxxxxxx [mailto:austechwriter-bounce@xxxxxxxxxxxxx] On Behalf Of Janet Taylor Sent: 08 September 2008 07:27 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
