How To Connect To Your Server Via FileZilla
Upon logging into your cPanel, identify the link called, "FTP Accounts"
Now you will find the administrator FTP account's username located in the "Special FTP Accounts"
Open your FileZilla and navigate to the credential bar and enter your FTP credentials. Your default host will be: "ftp.YOUR-DOMAIN.com", your username is what you got from the cPanel, your password is your cPanel password and the port is "21" by default.
Now choose if you want FileZilla to remember the passwords used.
Now you are connected to your webserver and you can start to edit your website. To get to the folder that houses your public files, you must go to /www or /public_html.
