You can change where the layers are stored using the docker-root configuration, as demonstrated in the Docker Engine on Windows documentation. Only NTFS is supported for layer storage.

Where are Docker builds stored?
In a default install, these are located in /var/lib/docker. During a new build, all of these file structures have to be created and written to disk — this is where Docker stores base images. Once created, the container (and subsequent new ones) will be stored in the folder in this same area.
What does a docker image look like?
A Docker image is made up of multiple layers. A user composes each Docker image to include system libraries, tools and other files and dependencies for the executable code. … A Docker web server image can also be used to build a container. Each image has one readable/writable top layer over static layers.
Can a docker image run on any OS?
You can run both Linux and Windows programs and executables in Docker containers. The Docker platform runs natively on Linux (on x86-64, ARM and many other CPU architectures) and on Windows (x86-64). Docker Inc. builds products that let you build and run containers on Linux, Windows and macOS.
What is difference between container and Docker?
