Compressed file used by Hauptwerk, an application that allows users to create organ music; contains components, such as temperaments, sample sets, or organs, that add functionality to the application; used similarly to a .PLUGIN file.

Do not attempt to extract or install component packages using third-party RAR software. Only use Hauptwerk's native component installer. To properly install a COMPPKG.HAUPTWERK.RAR file, select File → Install organ or temperament..., navigate to your component package, and click Open.
