FTP are known as File Transfer Protocol, a standard network protocol that is used for transfer the files from a server to a client on a compuet network. To upload the files through FTP, you will need a particular

Of course, you can use a different FTP client if you choose. To
connect with and FTP server, you need the following information:
· FTP server address. The FTP address should be
ftp://your-domain-name.com, where your-domain-name.com is your site’s
Internet address.
· FTP username. It is identical to your system username. Note that
the system username is different from the username that you use for
logging in to Plesk. To find what is the user name of your system, go to
Websites & Domains and click Web Hosting Access. You will
find it under Username. You can change username of your system if
you need.
· FTP password. It is identical to user password of your system. If
you do not know what is the user password of your system , Visit the option Websites &
Domains and click Web Hosting Access. You can reset the
password under Password.
To publish a website using FTP:

If you are at the back of a firewall, enable passive mode. Refer to your
FTP client documentation to understand how to enter passive mode.
2. Upload the files and directories of your site to the httpdocs
directory. If you are using the CGI scripts, put them in the cgi-bin
directory.
