Problems with Multiple File Download

[Darren Alexandria]

Good day!
I have a code that downloads multiple files from a database to a specified directory. It works well but when I check the contents of the file, somethis is wrong.

I have downloaded 16 files and only file # 4,5,6,7 have the correct contents. I don't know why.

Please help me.

here's my code;

 
 statement = connection.createStatement();
        rs = statement.executeQuery("SELECT strFileName,imgFile FROM tblTestFiles ORDER BY strFileName");
    
    
        while (rs.next()) 
        {

String filename = rs.getString(1);
            Blob blob = rs.getBlob(2);
          InputStream is = null;
          is = blob.getBinaryStream();
          int i;
String dir = "C:\\DownloadedFiles";
File path = new File(dir, filename);
FileOutputStream fos = null; 

fos = new FileOutputStream(path, true);

PrintWriter pout = null;
pout = new PrintWriter(new FileOutputStream(path,true));

       while ((i = is.read()) != -1)
{

   pout.write(i); 
}

fos.close();
pout.close();

         }// end of if construct
    }// end of try
     catch (IOException e) 
    {
    e.getMessage (); e.printStackTrace(); 
System.out.println(e); 
    } 
    catch (SQLException e) 
    {
    e.getMessage (); e.printStackTrace(); 
System.out.println(e); 
    }
 

Thanks.
