What is per-action object repository type in QTP?

When working in object repository per-action mode:

1. QuickTest creates a new (blank) object repository for each action. As you record operations on objects in your application, QuickTest automatically stores the information about those objects in the appropriate action object repository.
2. When you create a new action, QuickTest creates another new object repository and again begins adding test objects to the repository as you record.
3. When you record on the same object in your application in two different actions, the object is stored as a separate test object in each object repository.

When you save your test, all of the action object repositories are automatically saved with the test as part of each action within the test. The action object repository is not accessible as a separate file (as is the shared object repository).
