You can then open these text files in a text editor such as Notepad. If you want to make them HTML files again, all you have to do is change their extension to ".html" or ".htm".

Stupid question, and probably very easy answer. Basically, in XP, if I create a Notepad file on the Desktop, and name it something like 'index.html', the file shows up on the desktop as 'index.html'.
