QTP and Multiple Users

[Suba]

Thanks Basant. Your response was informative and very helpful to me.

In reponse to your answer, I have a following clarification.

Even though each user has QTP installed in their local machine, is it advisable -
A) To store the Test scripts with reusable Actions in a central location in one of our network location?
B) Then, each users can have their separate test folders using the same shared test script by coping but different Data set (through Datatable) in the same network location?

Please advise a better way to organize the test area, if any. My objective is to build reusable components which each users (testers) can assemble for their test as required.

Thanks
