Using filezilla ftp client is your second option.
This is a easier one for me as I use it to edit the site. http://www.siteground.com/tutorials/ftp10/filezilla.htm is a tutorial on how to use filezilla to access your site.
For the configuration details.. you can visit your cpanel and then find the ftp section and check for the configurations.
Those configurations are to be set in filezilla client and that opens up the site storage for you.
