Sound files in small basic?

[Waluigi time]

I have a small IT class project for school where I have to program an EV3 robot through the small basic extension.
I want the robot to play a sound file (a short rsf file) but I don't have access to all of the folders nor do I have access to the EV3 software...
The sound file I want to play was made at home using the EV3 software but I can't use the exported rsf in my code for some reason.
I have tried several things but without access to all the folders (I can reach several folders but not through the root so I can't reach the sounds folder) and the EV3 software I'm stuck...

Can anyone help me with the rsf without saving it in the sounds folder?
