Git - where are the files stored

Git - where are the files stored

I am new to git and to version control in general, so bear with me.
I followed the directions at
http://thelucid.com/2008/12/02/git-setting-up-a-remote-repository-and-doing-an-initial-push/
to create a git repository on a server. Note that it is a bare repository.
What I am unable to understand is where are the files stored on the
server. They are not present in the folder in which the repo is created.
The folder structure is like so (ls command):
branches config description HEAD hooks info objects refs
I cannot find the files (bunch of sql files) anywhere in here. So where
are they?
Note that git clone user@server.com:/path/to/repo from another local
machine works fine.
