Docker Toolbox - change machine location

Environment: Win 10, 64-bit

Installed Docker Toolbox.  It stores VM image on C: drive,
C:\Users\<USER NAME>\.docker\machine\machines\default

Want to move this to D: drive which is a large HDD, to save relatively smaller C: SSD.

1. Decide where to install on D: --> e.g.) D:\cloud_tools\docker\
2. Set up environment variables:
• DOCKER_CERT_PATH --> D:\cloud_tools\docker\.docker\machine\certs
• DOCKER_TOOLBOX_INSTALL_PATH --> C:\Program Files\Docker Toolbox
• MACHINE_STORAGE_PATH -->  D:\cloud_tools\docker\.docker\machine
3. Move everything under C:\Users\<USER NAME>\.docker\ to D:\loud_tools\docker\.docker\
4. Restart PC and try it.
