[Elecraft] K3 Utility Macro Editor

[Jim - WS6X]

G'day,
Can someone tell me where the K3 Utility Macro Editor saves its data files?
Or what file type is used? I'm using Win 10. The help files don't seem to
mention it, and an Internet search came up empty.
I find the saved configuration files, and the K3 Frequency / Memory Editor
saved data files, but am skunked on the saved macro files.
Thanks,
