Chapter 3: File Systems Section

The File Systems section of the configuration file is also known as FSMount. The File System section contains entries for a number of different features. This is because all configurable plug-ins and the variables they require are listed here. The plug-ins themselves are stored in a directory indicated by the PluginDirectory variable, described in Chapter 2: Paths, Ports, and Passwords.

Why the File Systems Section is So Large

All requests of the Helix Universal Server are processed by plug-ins, and all plug-ins are listed in the file system section. Plug-ins control which features are available to Helix Universal Server.

The modular plug-in design means that new features can be programmed and easily substituted for the existing plug-ins. New plug-ins may require different list arrangements and variables; check with the developer of the plug-in for this information.

The RealSystem SDK Developer's Guide provides developers with the public interfaces used to extend and customize RealSystem to stream new data-types, create new clients, or to customize Helix Universal Server by building a new plug-in.
