Building files into bin folder

I am working with a team in developing a project with JME3 and I noticed the two files:

From what I can gather, they are objects generated at build time as part of the graphics library. I was wondering what exactly these files were and if it would be possible to configure my project so these are built into the bin folder instead of the project folder?

They are the native libraries necessary to do sound and OpenGL. They are extracted where you run the application so that the OS can find them.

Is it specifically the OS that is looking for the libraries, or the application? I.e. doesnt the application tell the OS where to look?

Yes, the OS loads the DLL, else the application would not have to extract it.
