title: Alfresco - file already exists after file moved to another folder
body: <p>I use Alfresco 4.2.c on a Linux 64bit machine.2.c on a Linux 64bit machine. To insert files on Alfresco i've mapped \192.168.20.101:8080\alfresco as a network drive in Windows XP.</p>
  
  <p>i've developed a webscript in Java that takes as input the nodeRef of a file, then make an update of a metadata and at the end move the file from the initial folder to another folder. It works great and i'm very satiesfied for this!</p>
  
  <p>But i've a strange behaviour: i have a file named for example "fileA" in the folderA, i execute the webscript so the file is moved to folderB.
  If i try to insert through the mapped network another file in the folderA named "fileA" Windows says there is already a file named fileA in that folder so i have to cancel the operation...but in the folder i'm sure there is not such file and also if i go into repository i don't see a fileA in the folder A...</p>
  
  <p>Maybe i've to set something particular?
  Here is a snippet of code of the webscript:</p>
  
  <pre><code>newFileName = oldFileName + "_" + new Date().getTime();
  fileFolderService.move(docRef, childRef, newFileName);
  </code></pre>
