Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi there!

My brothers client is only 5.02GB from Nos download which is all fine, but here's the thing mine appears to be 5.09GB and I can't seem to find out why. Can anyone explain what extra 7 is?

I got it originally from Kronus a long while ago before I even knew about Nos, can anyone shed some light?

Thanks!

Differen't servers attach different addons etc. to them, plus Nos is an early vanilla patch, so none of the later raids (which might account for the missing 0.7GB.)

Thanks for answering it's not so much a big deal as I was wondering what the hell it was.
