Text editors

I have many pages (name.html) and on each I need to change the path to css and the path to the image.

Answer 3

Excellent program Emeditor
Open all html files in it at once, and then there is such a thing as search and autocorrect, click on the search for the desired path and substitute the desired new path for replacement, then the replace all button.
Save all files, you can just click close and apply to all. Voila, 2 minutes and you are all updated.
