title: How can I clean my .git folder? Cleaned up my project directory, but .git is still massive
body: <p>The <em><strong>.git/objects</strong></em> in my rails project directory is still massive, after deleting hundreds of Megabytes of accidentally generated garbage.    </p>
  
  <p>I have tried <code>git add -A</code>, as well as other commands to update the index and remove nonexistent files.  I gather, perhaps incorrectly, that the files with two character names in the directory are blobs.  I have tried rolling back to previous commits, but no luck.  </p>
  
  <p>What can I do to clean this directory?</p>
