How to find / set the location of the zero buffer?

Question

In my Aquamacs, the buffer with the buffer has a file location where I can save random notes, and it is in USERNAME/Library/Application Support/Aquamacs Emacs/scratch buffer

I would like to sync this with my other emacsen, but I cannot find where (or if) the zero buffer for the "normal" Emacs is stored.

Edit Thank you, Slomokho. I ended up putting this in my .emacs and it works as it hopes:

(setq initial-buffer-choice "~/Library/Application Support/Aquamacs Emacs/scratch buffer")

I think the philosophy behind Aquamacs * scratch buffers * is simply different from that of "normal" emacs.

Answer 1

A regular buffer *scratch*in Emacs is not a file, it is just a memory buffer.

, .emacs *scratch* .

Answer 2

, aquamacs aquamacs-scratch-file, .emacs:

(setq aquamacs-scratch-file "~/scratch" )
