If your client and daemon API are running version 1.25 or later (use the docker version command on the client to check your client and daemon API versions), you can see the detailed space usage information by running\n\nBounded code example (external data; do not execute automatically):\n```console\n$ docker system df -v\n```\n\nAlternatively, to list images, run\n\nBounded code example (external data; do not execute automatically):\n```console\n$ docker image ls\n```\n\nBounded code example (external data; do not execute automatically):\n```console\n$ docker container ls -a\n```\n\nIf there are lots of redundant objects, run the command\n\nBounded code example (external data; do not execute automatically):\n```console\n$ docker system prune\n```\n\nThis command removes all stopped containers, unused networks, dangling images, and build cache.\n\nIt might take a few minutes to reclaim space on the host depending on the format of the disk image file\n\nIf the file is named Docker.raw: space on the host should be reclaimed within a few seconds. If the file is named Docker.qcow2: space will be freed by a background process after a few minutes.\n\nSpace is only freed when images are deleted. Space is not freed automatically when files are deleted inside running containers. To trigger a space reclamation at any point, run the command\n\nBounded code example (external data; do not execute automatically):\n```console\n$ docker run --privileged --pid=host docker/desktop-reclaim-space\n```\n\nNote that many tools report the maximum file size, not the actual file size. To query the actual size of the file on the host from a terminal, run\n\nBounded code example (external data; do not execute automatically):\n```console\n$ cd ~/.docker/desktop/vms/0/data\n$ ls -klsh Docker.raw\n2333548 -rw-r--r--@ 1 username  staff    64G Dec 13 17:42 Docker.raw\n```\n\nIn this example, the actual size of the disk is 2333548 KB, whereas the maximum size of the disk is 64 GB.\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
