In the Checking Objects of Creating Checkpoint of QTP Tutorials i have a doubt.

In the Tutorials it is mentioned that

1.Start QuickTest and open the Recording test.
If QuickTest is not already open, choose Start > Programs > QuickTest Professional > QuickTest Professional.If the Welcome window opens, click Open Existing.
If QuickTest opens without displaying the Welcome window, choose File > Open or click the Open button .
In the Open Test dialog box, locate and select the Recording test, then click Open.

2.Save the test as Checkpoint.
Select File > Save As. Save the test as Checkpoint

How can we save the test as Checkpoint ?
