title: vba fso file exists works with mapped drive letter but doesn't work with unc path
body: <p>I've used <code>fso.FileExists(fullfilepath)</code> many times before, but always with mapped drive letters.  I have the reference to Microsoft Scripting Runtime.</p>
  
  <p>In my new situation, many people map the same drive letter to different paths, so I want to use the UNC path.</p>
  
  <p>I keep getting If <code>fso.FileExists(fullfilepath)</code> evaluating to false when I use the UNC path.</p>
  
  <p>If I use the mapped drive letter that I personally use, it evaluates to true - the file IS there, and the path name hasn't changed.</p>
  
  <p>I found some posts from people indicating they had problems when a folder in the path had spaces in the name, and the solution there was to wrap the fullfilepath variable in double-quotes, like </p>
  
  <pre><code>fullfilepath = Chr(34) &amp; fullfilepath &amp; Chr(34) 
  </code></pre>
  
  <p>but that didn't work either.</p>
  
  <p>I even pasted the paths in instead of using a variable.</p>
  
  <p>This works:</p>
  
  <pre><code>fso.FileExists("S:\pathpart\file.csv")
  </code></pre>
  
  <p>This does not work:</p>
  
  <pre><code>fso.FileExists("\\\networklocation\pathpart\file.csv")
  </code></pre>
  
  <p>I tried adding the Microsoft Visual Basic for Applications Extensibility 5.3 reference, it didn't make a difference.</p>
  
  <p>The file is not hidden or read-only.</p>
  
  <p>I'm completely stumped.</p>
  
  <p><strong>Edited to add the path, for clarity:</strong>
  <code>\\corp\sites\abc2001\MIS\Company\Sterling Data\Investments\branch_referrals_13JUN15.csv_13062015.csv</code></p>
