FrontPage Extensions are a group of system files and folders needed by sites designed with Microsoft FrontPage to operate properly. Without them, you may still use the app to build sites and upload your content on the web server, but the websites will have restricted features, thus the user experience won't be the same. An additional advantage of using a hosting service with FrontPage Extensions available is that you're 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 info in FrontPage. This characteristic will make it very easy to start and keep your web presence even if you lack any previous knowledge, because you can update the website later on just as easily.
