拉取图像时，设备上没有剩余空间

在Windows 10 Build 14393下使用Docker 1.13.0（9795），试图运行最新的python映像（将会是3.6）时，我得到“设备上没有剩余空间”：

> docker run -it python Unable to find image 'python:latest' locally latest: Pulling from library/python 5040bd298390: Pull complete fce5728aad85: Pull complete 76610ec20bf5: Pull complete 52f3db4b5710: Extracting [==================================================>] 129.8 MB/129.8 MB 45b2a7e03e44: Download complete 75ef15b2048b: Download complete e41da2f0bac3: Download complete C:\Program Files\Docker\Docker\Resources\bin\docker.exe: failed to register layer: Error processing tar file(exit status 1): write /usr/share/doc/libfreetype6/reference/ft2-type1_tables.html: no space left on device. See 'C:\Program Files\Docker\Docker\Resources\bin\docker.exe run --help'. 

硬盘上有20 GB以上的空间，所以我认为这个问题在Docker的虚拟机里面。 如何访问它来调查磁盘使用情况并在需要时进行清理？

docker images和docker ps -a没有识别出任何大的：

 > docker images REPOSITORY TAG IMAGE ID CREATED SIZE ubuntu latest f49eec89601e 2 days ago 129 MB d4w/nsenter latest 9e4f13a0901e 4 months ago 83.8 kB > docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES ae1e7c7b11ed ubuntu "/bin/bash" 10 minutes ago Exited (0) 9 minutes ago quirky_rosalind 

单独拉动没有帮助：
