mangos zero installation problem..Cant open/edit realmd file

[Calgrain]

In accordance to the installation guide... step 26... I cant open/edit the realmd in any Database management tool that I can get my hands on it just wont open.
And I don't know what to do from here on, guess ill ask what editor do you people use here and see if its something I haven't tried.
