There are several implementations of storage handlers. The Open Test Architecture infrastructure returns the handler object appropriate to the configuration of the servers and project on which the application is run.

The use of the handlers in your application is the same regardless of the implementation. Declare variables as type IExtendedStorage. 

Get a storage handler object from AttachmentFactory.AttachmentStorage, Run.ExtendedStorage, Attachment.AttachmentStorage, Test.ExtendedStorage, or TestFactory.RepositoryStorage.

Note that a storage handler object obtained from an object will not necessarily handle only items belonging to that object. For example, if you get a storage object from a test attachment and then download all attachments:

    Set TestAttachmentFactoryObj = aTestObject.Attachments
    Set TestAttachStorage = TestAttachmentFactoryObj.AttachmentStorage
    AttachDownLoadPath = TestAttachStorage.LoadEx("*.*", True, NullList, isFatalErr)

The result is to download all attachments in the project.

To avoid this, either specify a filter or use other methods. In the above example, you could replace the ExtendedStorage load with Attachment.Load.

The storage handler is also accessible from TDConnection.ExtendedStorage, but a reference obtained this way is disabled by the default security settings.
