To view your favorite websites offline
• Select the Make available offline check box
There is, unfortunately, a catch. In order to make a website available offline Internet Explorer must download it. This process is not a big deal if you only need one page, but if you want to peruse the links on the page, or worse still the links of the links, you are talking about quite a bit of downloading. You can set how many layers Internet Explorer downloads and how often it downloads them by clicking offline settings.
Tip: For those folks who aren't interested in offline settings (that is, most folks with broadband connections), click the small Less options button to truncate the favorites center box and hide the offline options.
