Transfer files from a USB stick to Windows 10 IoT Core local storage

I have a Raspberry Pi 3 running Windows 10 IoT Core. How can I copy files from a USB stick connected to the device to the local SD card storage? Is this possible using PowerShell?

Ideally I want to do this without the need for a UWP app running on the device and any interaction via a local GUI.

Currently when the device is running its default app and I insert a USB stick nothing happens like it does on a desktop edition of Windows 10.

To further clarify I also don't want to navigate to the devices storage via a UNC path copying files between network locations. The files have to be sourced from the USB stick.

Thanks
