title: git large pack file, delete and rewrite?
body: <p>I have a relatively small git repository containing a standard Wordpress installation. However, I accidentally added a "concept" folder in the repository which contains many large <code>psd</code> files.</p>
  
  <p>The problem is that now, after 50 commits, git has created a "pack" file, which is 1,3 GB. </p>
  
  <p>To downsize the pack folder I tried to remove my "concept" folder via:</p>
  
  <pre><code>git filter-branch --index-filter 'git rm -rf --cached --ignore-unmatch DIRECTORY/' --prune-empty --tag-name-filter cat -- --all
  </code></pre>
  
  <p>and afterwards</p>
  
  <pre><code>git gc --aggressive --prune
  </code></pre>
  
  <p>After the execution of these commands, my "concept" folder was deleted from the file system and from all commits but the pack file is still exactly 1,3 GB</p>
  
  <p>Is there anything else I can do to reduce the size of the pack folder?</p>
