With your own Virtual FTP Server, users can access your site via ftp.yourdomain.com. This not only makes your site more organized, but it allows users to distinguish your FTP server from your web server.
One can be used for downloading programs, while the other is used for viewing information. Virtual FTP Servers allow other guest users to download, upload or view files in your FTP directories on the hosting server. Anonymous FTP is typically available even if optionally.
