FrontPage Extensions are special system files, that are needed for websites created with Microsoft FrontPage to operate effectively on a web server. Without these files, the websites will still function, but some functions will be unavailable, which can instantly affect the user experience of your visitors. If FrontPage Extensions are available on the website hosting server, you can also upload the website which you've designed on your personal computer right away and with no additional software such as an FTP program. You will just need to enter the FTP sign in info for your web host account and FrontPage will do the rest, uploading or updating your files. Considering how easy it is to work with FrontPage, you will be able to launch your web presence quickly even when you have never created a website before.
