These are the naming habits that I find most helpful, so I've called them conventions. This has absolutely nothing to do with naming files on a desktop computer.
I'll be the first to admit that learning about naming schemes means things are not set in stone. Sometimes I try something different just to try it out, and prefer doing it for years before finally figuring out that it's not what's best.
So... I'd like to inform you that the guidelines from this section are fluid, they may or may not change.
Also, when you use something from here please feel free to rip it apart to see if you like doing it differently.
