How to recover removed Docker images/containers after upgrading Docker Toolbox on Windows 7?

Question

I had installed Docker Toolbox 18.03.0-ce on Windows 7 64-bit and had many pulled images and built containers. After upgrading Docker Toolbox to 18.09.1, there are no images and containers in results of these listings, but my networks, volumes and used space in Boot2Docker are as the same as before:

$ docker images --all
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

$ docker container ls --all
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

$ docker network ls
NETWORK ID          NAME                                  DRIVER              SCOPE
446f56b6ddde        bridge                                bridge              local
7ec9271f1395        downloads_default                     bridge              local
d35c380fb35e        host                                  host                local
12beb20e048f        none                                  null                local
af4825df71cd        temp_default                          bridge              local
2b91271536ac        net1_default                          bridge              local
...

$ docker volume ls
DRIVER              VOLUME NAME
local               c1a0b6eaea1d9bffa8ea1cff67fae47517f6cde6e7ff875c5264aba3a422a777
local               docker1_data
local               downloads_data
...

The old Docker Machine is also running as the same as before:

$ docker-machine.exe ls
NAME      ACTIVE   DRIVER       STATE     URL                         SWARM   DOCKER        ERRORS
default   *        virtualbox   Running   tcp://192.168.99.100:2376           v18.06.1-ce

But the size of the virtual disk of Boot2Docker is still 15GB:

$ ls -lh /c/Users/hamid/.docker/machine/machines/default/disk.vmdk
-rw-r--r-- 1 99777 1049089 15G Jan 20 11:41 /c/Users/hamid/.docker/machine/machines/default/disk.vmdk

Also in the running Boot2Docker, /mnt/sda1/var/lib/docker/aufs has 10.6GB size:

root@default:/# du -d1 -h /mnt/sda1/var/lib/docker
20.0K   /mnt/sda1/var/lib/docker/builder
36.1M   /mnt/sda1/var/lib/docker/image
20.0K   /mnt/sda1/var/lib/docker/plugins
8.0K    /mnt/sda1/var/lib/docker/overlay2
4.0K    /mnt/sda1/var/lib/docker/tmp
270.7M  /mnt/sda1/var/lib/docker/volumes
672.0K  /mnt/sda1/var/lib/docker/containerd
72.0K   /mnt/sda1/var/lib/docker/buildkit
4.0K    /mnt/sda1/var/lib/docker/trust
136.0K  /mnt/sda1/var/lib/docker/network
4.0K    /mnt/sda1/var/lib/docker/runtimes
4.0K    /mnt/sda1/var/lib/docker/swarm
10.6G   /mnt/sda1/var/lib/docker/aufs
3.9M    /mnt/sda1/var/lib/docker/containers
10.9G   /mnt/sda1/var/lib/docker

The main large folder is /mnt/sda1/var/lib/docker/aufs/diff that has about 300 folders. It seems that old files are still there. Is there any way to recover images or containers back?
