What is the Action Template and how to Create it?

Action Template:-
In our test, in every new action, if we want to include one or more statements like Headers (Author name, Creation date, Change log etc...), function calls, etc... We can create an action template(Text file) with these statements. Save it as ActionTemplate.mst in below path in local machine.
Path:- QuickTestInstallation Folder\dat folder.

Note: QTP identifying only the file name ActionTemplate.mst is recognized as an action template.
