Without going into the gory details, I need a program that will let me load half a dozen html files and bulk change (bulk search-and-replace) links that are now no longer correct.

Some of these pages go back 15 years and I was too stupid then to have used relative links....

I tried loading into Word and WordPerfect, but they load looking like webpages and not has html.

I assume I can use Notepad, but if there is something simpler/better, would love to be pointed at it.

Freeware please
