Frontpage Extensions allow you to publish your site directly from the FrontPage application. This means that you will not have to upload files through FTP, or another method.
Warning: Installing or uninstalling Frontpage Extensions will result in the loss of all ".htaccess" files in your web area. Any changes you have made to your ".htaccess" files will be lost. Any directories you have protected with WebProtect will become unprotected until you reprotect them.
