HTML Help File Type Chart

HTML Help involves many different components, each of which requires a different file type with its own extension and special requirements. For each of the possible HTML Help components, the following table shows: the appropriate Extension in HTML Help (plus the extension of the Windows Help counterpart, if any); the name generally used to refer to that File Type; the tool or application that the component is Created in; and the Purpose & Use of that component.

For additional information about using these file types, consult the Process Overview.
