    Are you sure that you connected to the "nRF USB" port along with the one you connect to power the device?

    Once you connect a usb cable to "nRF USB" port , then you can see that there are drives emulated in your system. You can drag and drop or copy/paste any files you want into them. I just tested it and it worked just file.

    To be able to read the contents using terminal com port, disconnect the cable from "nRF USB" port so that the terminal can connect to the MSC (since there cannot be two connections to the instance" and you can read the files using the buttons mentioned by steps in Andreas' reply.
