title: While in CMD shell, copying files from host OS to guest VM locks files (VMware Player/Workstation)
body: <p>We're running the latest versions of VMWare Player and Workstation for Windows. The following behavior is identical across both products.</p>
  
  <p>Problem: We open a CMD prompt in our guest OS (XP, Vista, Windows 7) and copy files from our host OS using the standard CMD shell copy command:</p>
  
  <p>copy z:\C$\testfiles </p>
  
  <p>The copy completes successfully, but from that point forward, all the files that were copied to our guest OS are now LOCKED on our host OS.</p>
  
  <p>This does not happen if we use Windows Explorer to copy files - it only happens when files are copied via the CMD shell.</p>
  
  <p>As mentioned at the start of this question, this behavior is reproducible in both VMWare Player and VMWare Workstation across multiple machines and multiple guest OS's.</p>
  
  <p>I've googled for a workaround, but without success.</p>
  
  <p>Any ideas appreciated.</p>
