The htc file extension is generally used for files that contain HTML Component data.
For Microsoft Internet Explorer 5 and later, HTML Components (HTCs) provide a mechanism to implement components in script as Dynamic HTML (DHTML) behaviors.
The htc file is an HTML file that contains script and a set of HTC-specific elements that define the component. The component is saved with an htc extension. This section lists these HTC-specific elements and the members they support.
MIME types:
text/x-component
Use text editor or specialised application like Adobe Dreamweaver to open and edit the *.htc file.
You can also open it in any web browser (Internet Explorer, Firefox).
Conversion to other formats seems to be possible with compatible tools.
