Creates this file, if it does not exist. Also creates any ancestor folders which do not exist. This method does nothing if the file already exists and is a file. @throws FileSystemException If the file already exists with the wrong type, or the parentfolder is read-only, or on error creating this file or one of its ancestors.

                // item is not processed by any other parties
