The platform's media browser is where all uploaded media (images/Fonts ect...) are stored. From the media browser users can also download files and generate the Public Path for coding. The media browser is individual to a domain and so the Public Path will always be unique to that domain.
Media browsers can be organised via folders or, as they're known in the system, directories.
Font files can also be uploaded into the system to then be referenced in a portal page's CSS. Font files should be uploaded directly into the Media Directory.
