Once you have your FTP Client you will see a box that says “Host”, “Username”, and “Password”. Host is where you would put the IP Address or domain name of your website. Username and Password is where you would put the username and password from your web hosting account. Once you have filled that information in, click Connect and you will see it start connecting to the server. If you have successfully connected you will see the files show up on the right side of the screen. Once you have connected, you can start to transfer files to the server. To do this either double-click on the files you want to upload or right-click and select upload.
