Can anyone guide where we can look for File upload/download programs in BaaN V8.9a3 so to understand what are the input/output parameters of file and file format.

I moved this to the tools forum since it seemed like a question that someone can answer in this forum. You can always try searching this forum for exactly what you are trying. I would need more information on what you mean by file upload and download programs. Now someone familiar with your version might now right off hand what you are referring to.

Try providing more information on what you are looking for - or trying to do? Not everyone visits the site everyday so it might take a while to get an answer.
