title: How to discover Oleobject ClassType of files?
body: <p>I'm stuck how to determine files' Classtypes needed to use in code to embed these files into a Word document:</p>
  
  <pre><code>Selection.InlineShapes.AddOLEObject ClassType:="AcroExch.Document.11", _
          FileName:="C:\Work\Dashbaord &amp; ".pdf", LinkToFile:=False, _
          DisplayAsIcon:=False
  </code></pre>
  
  <p>I need to embed csv, pdf, xlsx and txt files. How I can automatically loop all files in folders and automatically determine the <code>ClassType</code> of each?</p>
