This is an improvement of the selected answer because that answer is limited to c:\Users folder. If you want to create a volume using a directory outside of c:\Users this is an extension.

In windows 7, I used docker toolbox. It used Virtual Box.

1. Open virtual box
2. Select the machine (in my case default).
3. Right clicked and select settings option
4. Go to Shared Folders
5. Include a new machine folder.

For example, in my case I have included:

**Name**: c:\dev
**Path**: c/dev

6. Click and close
7. Open "Docker Quickstart Terminal" and restart the docker machine.

Use this command:

$ docker-machine restart

To verify that it worked, following these steps:

1. SSH to the docker machine.

Using this command:

$ docker-machine ssh

2. Go to the folder that you have shared/mounted.

In my case, I use this command

$ cd /c/dev

3. Check the user owner of the folder. You could use "ls -all" and verify that the owner will be "docker"

You will see something like this:

docker@default:/c/dev$ ls -all
total 92
drwxrwxrwx    1 docker   staff         4096 Feb 23 14:16 ./
drwxr-xr-x    4 root     root            80 Feb 24 09:01 ../
drwxrwxrwx    1 docker   staff         4096 Jan 16 09:28 my_folder/

In that case, you will be able to create a volume for that folder.

You can use these commands:

docker create -v /c/dev/:/app/dev --name dev image
docker run -d -it --volumes-from dev image

or

docker run -d -it -v /c/dev/:/app/dev image

Both commands work for me. I hope this will be useful.
