I have this service...

```
storage:
 image: mcr.microsoft.com/azure-storage/azurite
 ports:
  "20000:10000"
 restart: unless-stopped
 volumes:
  C:/Data:/hello

```

I can add data to the Azurite service and I can browse it in the volume via Docker Desktop but I can't see any files in my local file system - the folder is always empty.

Why isn't the volume mapped to my file system?
