FrontPage Extensions are a set of system files and folders needed by sites designed with Microsoft FrontPage to operate correctly. Without them, you may still use the application to make websites and upload your content on the web server, but the sites will have limited features, thus the user experience will not be the same. An additional advantage of using a web hosting service with FrontPage Extensions available is the fact that you'll be able to publish your webpages directly on the server without the need for any third-party software as long as you enter your account FTP details in FrontPage. This feature will make it very easy to start and maintain your web presence even if you do not have any previous knowledge, as you are able to update your website in the future just as easily.
