Windowsfilter folder is filled with image data

Docker Desktop for Windows
1

I’m running Docker for Windows on Windows 10 Professional. I’ve been pulling, building, running, pushing images like crazy. I have stopped and removed all of my containers and removed all images yet my hard drive is still chock full of image data in the C:\ProgramData\Docker\windowsfilter folder. There is 21 GB of data in the windowsfilter folder. When I browse in it is clearly mostly windowsservercore and nanoserver due to the folder structure and the folder sizes.

Is there anything I can do to tell docker to purge this stuff?

What’s the output of docker images? Running docker rmi -f <image> should clean things up.

As I think I stated in my original post I didn’t have anything listed when doing docker images.

I managed to get it resolved by using the scary docker-ci-zap.exe utility referenced in this post https://github.com/docker/docker/issues/26873

Add -removing suffix to the folders in windowsfilter and restart the docker.
