Windows 10 - Location of docker image?
windows systray -> docker for windows -> docker settings -> advanced -> disk image location
result, something like
C:\ProgramData\DockerDesktop\vm-data\DockerDesktop.vhdx
This thread might help. Essentially, according to Michael Friis, docker images are stored in the Hyper-VM and the Hyper-V VM harddrive itself is usually in C:\Users\Public\Documents\Hyper-V\Virtual hard disks.
