They usually will be purged, too. However, the NDP sections will be skipped if already processed once that day, to prevent repetitive executions during runs. So, if the "once a day" rule fires, NDP sections will be untouched, and thus not be purged right away.
Deleting manually might give you verification errors, since WOU still wants to verify their hashes. But, if you delete the contents of .\client\md and do a new run, all hashes verification AND once-a-day rules will be reset. The hashes will reappear, though.
