This article explains how to delete multiple defects at the same time.
I have hundreds of defects, and would like to delete them. Is there a way to delete them all at once, or do I have to delete them one by one?
In order to delete all the defects at the same time, highlight the first defect, hold down shift & alt at the same time. Right click and you will see an option which states: Delete defect and rest of set. When you select this you will receive a message box, choose Yes to all. This will delete all of the defects at once. See attached screen shot for more information.
