FrontPage Extensions are a group of system files and folders needed by websites created with Microsoft FrontPage so as to perform properly. Without them, you could still use the application to make websites and upload your content on the web server, but the websites will have restricted features, thus the user experience will not be the same. Another advantage of using a website hosting service with FrontPage Extensions available is that you'll be able to publish your web pages directly on the server without the need for any third-party software as long as you enter your account FTP details in FrontPage. This characteristic will make it very easy to start and maintain your web presence even if you don't have any previous knowledge, since you'll be able to update your website later on just as quickly.
