Can't find my id number anywhere in bf2

[sgtsam150892]

Ive looked at a thread which i can't remember where it is and searched for my player id number in a certain file. Only problem is that the file is not there. I have searched for the file through start ( right click ) search but no luck.
Can anyone help me with this?
Also what is X_Fire ID and where can i get it?

For your player ID number, I would search using www.BF2s.com

Also, XFire is a application that lets you see what your friends are playing and on which server. It also lets you join with one click.

Visit www.xfire.com for more information.
