htaccess

Hi,

I just install multisite to my wordpress and I find some difficulties. First: I am confused with .htaccess of my network. Where can I find it? Is it in my root directory or in other folder?

I want to modify my htaccess as to redirect my second website from blogger to my wp network. As I follow instruction for single wp, my network resulted in error 500.

Please help. Need solution here.

Thanks everyone
