Files for Blogs and Podcasts
Blogs and podcasts are the exception to the file structure rule. Each blog or podcast that you create has a single folder inside the site folder. Inside this folder are the HTML files for each post that you create. It also contains the HTML files for the blog or podcast main page and archive page. The main pages are named with the name that you give the blog or podcast, and the archive pages are named archive.html. Again, each page (entry, main page, and archive page) has a correspondingly named folder for images and other related files (including the media files that are podcast episodes).
Blog and podcast entries are not named using the names you give each entry or episode. Instead, iWeb generates long alphanumeric stings for each HTML file and corresponding folder, which can make identifying individual entries for editing difficult. This is one reason why editing elements on blog and podcast entries can be cumbersome.
You might also want to make changes to multiple entries (or even to every entry). The use of a global search-and-replace feature to locate text on multiple entries and make changes across the board, offered by several Web design tools, can make this easier if you want to make changes to every entry. In fact, this is essentially the approach that iWeb enhancer uses.
