  while (appIter.hasNext())

  {

  wt.content.ApplicationData syAppData = (wt.content.ApplicationData)(appIter.next());

  String docName = syAppData.getFileName();

  long fileSize = syAppData.getFileSize();

  String syContentFileName = outputDir + ((outputDir.endsWith("\\")) ? docName : "\\" + docName);

  // Save the content file to disk on the Windchill server
