How to save an image in docker toolbox

I use the Docker Toolbox on Windows 10 Home.

I would like to save the image and save it, but it seems that it will be banned because it runs on VirtualBox.Also, I don't know where to save it.

Is there any way to write an image to a file and save it?

↓Error Message

$docker save image_uwsgi-nginx-flask_full_set:latest>image_uwsgi-nginx-flask_full_set.tar
bash: image_uwsgi-nginx-flask_full_set.tar: Permission denied

If you are using the Docker Quickstart Terminal in the Docker Toolbox, there are drives mounted in the host environment such as /c, so docker save will be saved in the host environment.

For example:

nek MINGW64~
$ pwd
/c/Users/nek

nek MINGW64~
$ docker save piyo:latest>piyo.tar

nek MINGW64~
$

Then piyo.tar is stored in the host-side C:\Users\nek.
