A MIME Type object represents a MIME type registration or unregistration.
Registration or unregistration of a MIME type is controlled by its component and its file extension or COM class. The details differ somewhat between Tarma Installer and Windows Installer.
| Situation | Tarma Installer | Windows Installer |
|---|---|---|
| Not linked to a component | The MIME type is registered if its file extension or COM class are registered. |
The MIME type is registered if its file extension or COM class are registered. The MIME type's own component, if any, is ignored. |
| Linked to a component | The MIME type is registered if its component is installed. |
To register a file extension or COM class, you must create the corresponding File Extension or COM Class objects in the project and set the MIME type's Extension or Class ID fields (see below) to their file extension or CLSID. See File and MIME Types for more information.
