I have been using function files to store a particular action while working in automation projects using Keyword Driven framework.
I have been assigned to a new project where somework has already been completed in terms of framework designing.

The team earlier working on this project has used "QTP Actions" instead of Function files.

I agree we can use either Action files or Function files in the Keyword driven framework. Want to explore the Advantages and Disadvantages of using Action Files over Function files in Keyword driven framework in QTP.
