The **`/var/lib/docker/`** folder is the default Docker folder for Ubuntu, Fedora, and Deblan in a standard engine installation, used to store container images and logs.
To change the Docker folder:
1. Stop the Docker daemon.
**`sudo service docker stop`**
2. Create a file called **`daemon.json`** under the **`/etc/docker`** directory with the following content:
```
{
"data-root": "<path to your Docker folder>"
}
```
3. Copy the current data directory to the new one.
**`sudo rsync -aP /var/lib/docker/ <path to your Docker folder>`**
4. Rename the old docker directory.
**`sudo mv /var/lib/docker /var/lib/docker.bkp`**
5. After confirming that the change was successful, you can remove the backup file.
**`sudo rm -rf /var/lib/docker.bkp`**
6. Start the Docker daemon.
**`sudo service docker start`**
