Hi Cenk, Yes that helped a lot! Thank you :D But now I have another doubt: let's say my folder/project is the directory "A" in the folder example of RIOT, before your answer I thought that all the folder A would go to the board, so to see if my project was too big to fit into the board I would simply right click on the folder A, then properties and I saw how big was the folder, but now from your answer I got that only a binary, plus other modules configured in the makefile go to the board. Right? Well, then how can I know the size of that "binary plus the other modules" which goes to the board? So I can see if my project is to big or not.
