How to send text files and gameobjects through Sharing Service

Hi, I have two applications, one for my PC and one for my HoloLens which communicate through the Sharing Service application given in the Shared Holograms tutorial. As mentioned in the question, I want to transfer text files and gameobjects(.obj files) between the two devices through this server during runtime. And, preferably in a way in which all the devices connected to this server (if more HoloLens devices are connected for the sharing experience) have access to those files.

Could someone please explain how this can be done.

Thanks, Pranav
