FrontPage Extensions are system files which need to be present on a web server for specific features of websites created with Microsoft FrontPage to function appropriately. In case these files aren't on your server, your Internet sites will still work, but with limited functionality and they will probably display errors every so often. In addition, if your hosting supplier has FrontPage Extensions on their servers, you'll 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 should do is to enter you website hosting account FTP details in the FrontPage settings and the application will do all the rest. Future updates can be done in exactly the same way, making FrontPage an excellent option for people with little or no experience.
