How to allow StringTemplate.NET to load template files with the extension ".dwt"?

Question

The default template file extension for StringTemplate is ".st". Now I have several template files in the folder, and their extension is ".dwt". Is there a way to change the default template file extension and load all of them as shown below:

StringTemplateGroup group = new StringTemplateGroup("views", viewPath);

Answer 1

A pretty big hack that might work is to copy all the templates to the temp directory, but with the correct extension type by default.
