   public FileUtil() 

Default constructor

   public static void deleteAll(File f)  throws IOException

Given a directory or file, recursively delete all files and directories contained within, then delete the directory/file itself.

   public static File getTemporaryFile(File sourcePath) 

Given a file, return a file which is a temporary file in the same directory.

Parameter	Description
sourcePath	the extant file

   public static void replace(File sourcePath, 
                              File destPath) 

Given a source file path and dest file path, move the file. However we need to be careful to do the move in stages, because we want to handle power outages gracefully.

Parameter	Description

destPath	the destination

   public static int streamCopy(InputStream source, 
                                OutputStream dest)  throws IOException
