title: TFS creates a $tf folder with gigabytes of .gz files. Can I safely delete it?
body: <p>I am using visual studio 2012 with Microsoft TFS 2012.</p>
  
  <p>On the workspace that is created on my <code>c:</code> drive, a hidden folder <code>$tf</code> is created. I suspect TFS from creating this folder. It's lurking diskspace as the current size is several gigabytes now and it's about 25% diskspace of the total amount of gigabytes needed for the complete workspace. So this hidden <code>$tf</code> folder is quite huge.</p>
  
  <p>The structure is like this:</p>
  
  <pre><code>c:\workspace\$tf\0\{many files with guid in filename}.gz
  c:\workspace\$tf\1\{many files with guid in filename}.gz
  </code></pre>
  
  <p>Does anyone know if I can delete this <code>$tf</code> folder safely or if it is absolutely necessary to keep track of changes inside the workspace? </p>
