FrontPage Extensions are a number of system files and folders needed by sites created with Microsoft FrontPage to function efficiently. Without them, you could still use the application to make sites and upload your content on the web server, however the sites will have restricted features, thus the user experience won't be the same. Another advantage of using a website hosting service with FrontPage Extensions available is that you are 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 attribute will make it quite simple to start and keep your web presence even if you lack any previous knowledge, since you'll be able to update your website later on just as fast.
