FrontPage Extensions are system files which have to be available on a web server for certain features of sites designed with Microsoft FrontPage to function properly. If these files aren't on your server, your Internet sites will still operate, but with restricted features and they will probably display errors from time to time. Furthermore, if your hosting supplier has FrontPage Extensions on their servers, you will be able to publish your content directly from the program, eliminating the necessity to employ any third-party FTP client in order to upload files. All you need to do is to enter you hosting account FTP information in the FrontPage settings and the software will do the rest. Future updates can be performed identically, making FrontPage a fantastic option for people with little or no experience.
