title: What's causing xcopy to tell me Access Denied?
body: <p>The postbuild task for one of our solutions uses xcopy to move files into a common directory for build artifacts.  For some reason, on my computer (and on a VM I tested), the xcopy fails with "Access Denied".  Here's what I've done to try and isolate the problems:</p>
  
  <ul>
  <li>I tried a normal copy; this works.</li>
  <li>I double-checked that none of the files in question were read-only.</li>
  <li>I checked the permissions on both the source and destination folder; I have full control of both.</li>
  <li>I tried calling the xcopy from the command line in case the VS build process had locked the file.</li>
  <li>I used Unlocker and Process Explorer to determine there were no locks on the source file.</li>
  </ul>
  
  <p>What have I missed, other than paranoid conspiracy theories involving computers out to get me?  This happens on my dev machine and a clean VM, but <em>doesn't</em> happen for anyone else on the project. </p>
