Why are my Files Acting Weird?

I was told in another forum that I should expect a new "MPlog.log" file to be generated in either "programdata/microsoft/windows defender/support" or "windows/microsoft antimalware/support" whenever i run a new offline scan, but each folder only contains one such file despite me running that type of scan multiple times.

I also noticed each folder contained a number of files called "MPDetection.log", but in each folder the quantity of such files was lower than the number of offline scans I've run (a few in the "windows" folder, and only one in "programdata").

The "MPLog.log" file in "programdata" also doesn't seem to record any offline scans as far as I can tell.

In general both folders seem a bit different, so i assume they serve different purposes—what's the purpose of each folder, and why do I have less logs than scans I've run?
