This is in contrast to the many data types than Navigator already handles internally. Plugin technology can be thought of as being 'modular'. You add the component and it functions relatively seemlessly as if it were part of the host program. New plugins are being developed at a rapid pace as the industry recognizes the value of this kind of open technology. How to make them work Helper apps require that they not only be installed on the computer, but be configured within Navigator.
Navigator employs several default types natively.
In order to add an entry for a new type, several parameters must be defined. File type and subtype, the filename extensions, and the action to perform. Plugins override Helpers. If you have a plugin and a helper installed for the same file type, the plugin will attempt to respond to activities relating to that file type. To disable a plugin one may manually relocate or rename the primary plugin file.
