Finding _sfx names

[Topknot001]

So had an idea to use other types of "_sfx" sounds for different actions that people can do on the server. One thing I can't seem to find the link on is where or when is the sfx sound files named or how are they called upon.
Example: (I find this in the CfgSounds.hpp)

class z_tentunpack_0 {
    name = "";
    sound[] = {"\dayz_sfx\effects\action_tentunpack_0.ogg",0.2,1,50};
        titles[] = {};

And later in the scripts I find the ability to "call" the sfx like this:

_sfx = "tentunpack";

So where did the "name" from z_tentunpack_0 change to tentunpack..? Am I missing an additional call or rename somewhere or is that just how the game calls the files?

Thanks

Ok let me refine my question a tad incase someone's got a nifty tip or pointer to lead me to go check out.
Here's examples of some of the calls for Sound FX's from various actions in Dayz.

_sfx = "repair";
_sfx = "cook";
_sfx = "gut";
_sfx = "refuel";
_sfx = "chopwood";
_sfx = "tentunpack";
_sfx = "fillwater";

Yet in the actual Dayz_sfx\effects folder we find names like:

action_cook_0.ogg
action_cook_1.ogg
action_cook_2.ogg
action_gut_0.ogg

So when in game the command _sfx = "cook"; is there someplace that the game reads the three mentioned above sound effects names for cook and makes an array and then end's up letting you call them with just "cook"?
