I’m not sure what your goal is and why you ask it in the Docker Hub category (I will move the topic), but you can’t just move images to an external hard drive. You could move the entire Docker data root but not with Docker Desktop. If you have Docker Desktop, you could try to move the virtual machine’s disk to an external hard drive. Or maybe you mean you want to export images, but you must have a final goal with it and I’m also not sure the right solution is to export images. You should use a registry and push the images to the registry. Do you want to work in an offline (air-gapped) environment where you can’t pull the images from the registry?
