[Noob] Trouble finding data folder

[Sithius]

Hai,

First of all, I'd like to start out with pointing out I'm no pro, or anything close to being that. I saw some videos on the internet where people had model edited and I wanted to try it out. So here goes;

I downloaded Glitchys suite and installed it on my computer, not in my wow folder as I've read you shouldn't do. Then I downloaded Kyx's WoWMe and installed it into my WoW folder. I simply followed Glitchys tutorial / random posts.

Now for the issue;

I want to edit my Night elf male, to Tauren male / NE female. But when I enter Glitchys suite and I enter all the information needed in the race changer(Used the patch-5.MPQ) except the MPQ spot. I cant seem to find my data folder;/ only in the public test realm. Which isn't what I need.
I've entered the following information;

Race Changer question: Your wow data path.
And thats what I cant find. And then I of course cant find the MPQ save location either.

So thats my question, I'm sorry for my noobishness, although I've spent a solid amount of time looking for a solution I'm unable to find one. (I've read a lot of posts, although some might seem similar they're not.)

Help my find my data folder please

Thanks a bunch in advance, any help is warmly accepted.

-Best regards, Martin.
