FrontPage Extensions are a number of system files and folders needed by sites made with Microsoft FrontPage to operate properly. Without them, you could still use the application to make sites and upload your content on the web server, but the sites 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 the fact that you're able to publish your pages directly on the server without the need for any third-party software as long as you enter your account FTP information in FrontPage. This characteristic will make it very easy to start and keep your web presence even if you do not have any previous knowledge, since you can update the website later on just as quickly.
