Accessing video files on Server 2012R2 file server

Here is my question, I load software on a win 8.1 system and add folders that are mapped to a Server 2102R2 file server. The XBOX can see them how? Do I add an app to the XBOX? Should I install on the 2012R2 server box instead since that is where the folders
reside?

Thanks for your help

To add this happens even when the video file is local and before being uploaded to Xbox server

We understand where you come from; However, we don't have any kind of control over the in game servers. For any in game servers related issues, we highly suggest contacting the developer of the game and letting them know about your request.

It not a issue Microsoft rules don't allow players to mod the files ie for us to mods the dayz or run mods like what you have on the pc you have to have access too the init.c file and other files like this on the server and because of the rule. bohemian won't allow nitrado to give us access too any other files but the xml files

I'm pretty sure pictures and video's don't save in a file on your HDD or MU. You only have 6 file share spots for this reason------>they are saved via online servers. You can upload your file shares to youtube but that's about it.

you cant access the files on the one S, you cant even transfer the world from xbox to pc, you will have to create a brand new world and host this from your server, i had to do the same so i now run a minecraft server for my kids that is always there when
they want to use it, remember to create daily backups of the servers files.
