Writes to MpWppTracing-%d-%n-00000003-ffffffff.bin file?

Question

Anyone ever seen any odd with a file named like this:

"C:\ProgramData\Microsoft\Windows Defender\Support\MpWppTracing-20190202-183619-00000003-ffffffff.bin"

Odd defined as conitnual writing for extended periods at fairly high speeds (relative to any other Windows instasll) Obviously it's some sort of Defender related file, but on most of my machines not much happens with that file (1-2KB/sec of writes). On my machine running DrivePool, I'll go through phases where it's writing to that file continually at 300-400KB/sec, sometimes more. It's only a 4K file so that seems a little excessive, and it's particularly annoying because I have All Defender related things turned off on this machine. Obviously something Defender related is still doing something though. Anyway, since this machine doesn't do anything but run DrivePool for me, I thought I'd check here.

Thanks!
