FYI SFTP is FTP over SSH. To use SFTP in Filezilla, you just select it from the 'protocol' drop down in 'Site Manager'. Then you also need to select either 'normal' (if you want to save your password in Filezilla) or 'Ask for password' (if you want to type it in each time). 'root' is the username.
Answer: Tools > File manage.
Sorry about guys. I spead about 1 hour searching before posting. Ended up stumbling on it.
