FTP via an FTP client
An FTP client is little program that you download and run on your desktop PC, you use it to copy files from one computer to another using the File Transfer Protocol. Use an FTP client such as SmartFTP, Filezilla or BulletProof FTP. Some FTP clients are available for free download.
For security reasons FTP access is automatically locked after 28 days and can be unlocked via the control panel.  You can unlock the FTP service by time or by IP address.
Please note that your website files will be located in the /public_html/ folder.
Via the Control Panel
Log into the Control Panel, and click on the File Manager icon. Once there, select the /public_html/ folder, this gives you options to upload files from your local computer.
