For large repositories, GIT will periodically perform a garbage collection to remove any unnecessary objects and compress refs(pointer to commits in GIT) into a single file for more efficient performance.
So the ref in .git\refs\branches will be moved a single file (i.e packaged-refs) after the command.
BTW… Git maintains information regarding the fetched branches, head, merge-head, etc in files in .git folder…
Again it is pointer having commit hash tag in it.

Same as Git Remote(It basically shorten the long remote urls to something of shorter name)
It basically maps the local repository to a remote repository however a bit different format.. Here is what git-scm.com says
Suppose you add a remote like this:
$git remote add origin https://github.com/schacon/simplegit-progit
It adds a section to your
.git/config file, specifying the name of the remote (
origin), the URL of the remote repository, and the refspec for fetching:
fetch = +refs/heads/*:refs/remotes/origin/*
The format of the refspec is an optional
+, followed by
<src> is the pattern for references on the remote side and
<dst> is where those references will be written locally. The
+ tells Git to update the reference even if it isn’t a fast-forward.
With refspecs you tell git what to push/fetch where and how to map local refs to remote refs and vice versa.
When you clone a repository git sets up the default refspec, you can see it in .git/config in the repository:
- what the heck is Reflog?
It keeps the history of whatever you do in the repository in the chronological order.
