title: How to delete all frames in H2O?
body: <p>I accidently imported more data into 0xdata's h2o flow than I actually intended. How can I delete all my data frames?</p>
  <p>I already tried <code>Data -&gt; List All Frames -&gt; Delete</code>, but I get the following error message:</p>
  <blockquote>
  <p>Error evaluating cell</p>
  <p>Error calling DELETE/....ink</p>
  <p>Object 'nfs:....lnk' not found for argument: key</p>
  </blockquote>
  <p>Is there another way to erase those data frames? Where are those data frames physically stored?</p>
