Files can be uploaded via the System > File Manager in the backend administration. Once there, you will be presented with a list of files and folders on your site that contain elements used within the site itself. You have the ability to create folders for organizational purposes as well as upload files to these and any existing folders.

Click ‘File Upload’ to select the folder you wish to load your file into (using the ‘Insert Into’ icon to its right) and you will then be presented with the option to browse files and folders on your computer and upload them to the website.
