FrontPage Extensions are a group of system files and folders needed by sites designed with Microsoft FrontPage so as to operate correctly. Without them, you may still use the app to build websites and upload your content on the web server, yet the websites will have limited features, thus the user experience will not be the same. Another advantage of using a hosting service with FrontPage Extensions available is that you are able to publish your webpages directly on the server without using any third-party software as long as you enter your account FTP details in FrontPage. This attribute will make it quite simple to start and maintain your web presence even if you lack any previous knowledge, because you are able to update the site later on just as quickly.
