Problem deleting file

Hi all,

I am currently developing a java application that uses a CSV file
which it reads and then populates the items inside a JList. Then the
user is able to delete an item from JList which then writes the
information to a temporary file. Once the data has been written I then
want the original file that it read in to be deleted. However for some
reason it keeps on failing and saying the deletion failed but I do not
understand. Below is the code that I am using in order for the item to
be removed from the JList and then written a the file with the new
information and also with the function where it is deleting the file:

public void btnDelete_actionPerformed(ActionEvent e) {
     int index = lstComputerExceptions.getSelectedIndex();
          model.remove(index);

          int size = model.getSize();

          if (size == 0) { //Nobody's left, disable firing.
              btnDelete.setEnabled(false);

          } else { //Select an index.
              if (index == model.getSize()) {
                  //removed item in last position
                  index--;
              }

              lstComputerExceptions.setSelectedIndex(index);
              lstComputerExceptions.ensureIndexIsVisible(index);
              String computerName = model.toString();
              StringTokenizer st = new StringTokenizer(computerName,
"[]");
              String tokenizedString = st.nextToken();

              String newComputers = tokenizedString.replace(",",
"\n");
              System.out.println(newComputers);
              try {
       BufferedWriter out = new BufferedWriter(new
FileWriter("C:\\Documents and Settings\\All Users\\Application Data\
\Remote Shutdown\\ExceptionsListTemp.csv"));
       out.write(newComputers);
       out.close();
       deleteOldFile();
       } catch (IOException ex) {
       statusBar.setForeground(Color.red);
       statusBar.setText("Failed to modify file. Please ensure
the file is not open");
       System.err.println("Unable to delete: " + ex.toString());
       }
          }
       }

    public void deleteOldFile() {

     try {
     File file = new File("C:\\Documents and Settings\\All Users\
\Application Data\\Remote Shutdown\\ExceptionsList.csv");
     boolean success = file.delete();

     if (!success){
     System.out.println("Deletion failed.");
     statusBar.setForeground(Color.red);
     statusBar.setText("Unable to modify changes. Changes have not
taken affect. ");
     }
     else{
     System.out.println("File deleted.");
     }
     }
     catch (Exception e) {
     System.err.println("Failed to delete the file: " +
e.toString());
     }
    }

For some reason when the file gets deleted it keeps on going into the
same part of the program where it says:
     if (!success){
     System.out.println("Deletion failed.");
     statusBar.setForeground(Color.red);
     statusBar.setText("Unable to modify changes. Changes have not
taken affect. ");
     }
I cannot work ou the reason for this.

Any help in this matter would be highly appreciated.

Thank you
