FrontPage Extensions are system files which have to be available on a web server in order for specific features of sites made with Microsoft FrontPage to operate appropriately. If these files are not on your server, your websites will still operate, but with restricted features and they will probably display errors every now and then. Furthermore, if your hosting supplier has FrontPage Extensions on their servers, you can publish your content directly from the program, eliminating the need to use any third-party FTP client in order to upload files. All you need to do is to enter you website hosting account FTP details in the FrontPage settings and the application will do the rest. Future updates can be done identically, making FrontPage a fantastic option for people with minimum or no experience.
