The original default file location specified for audio in both WinWarbler and DXKeeper was "C:\User\Andy\OneDrive\DXLab\QSOAudio". On startup the applications would create an empty DXLab folder. They did not create the QSOAudio folder.
After changing the path in both WinWarbler and DXKeeper to my preferred location, the applications continue to create an empty DXLab folder in "C:\User\Andy\OneDrive" when they start.
That's not a problem, just a minor annoyance. Very minor.
