FrontPage Extensions are special system files, that are needed for sites created with Microsoft FrontPage so as to operate effectively on a web server. Without these files, your sites will still function, however some functions will be unavailable, that will immediately affect the user experience of your site visitors. When FrontPage Extensions are available on the hosting server, you can also upload the site that you have made using your PC straight away and devoid of additional software such as an FTP program. You'll just need to enter the FTP sign in data for your web host account and FrontPage will do all the rest, uploading or updating your files. Taking into consideration how easy it is to use FrontPage, you'll be able to start your online presence in no time even in case you have never made a site before.
