Javamail Getting one extra file On downloading attachments

Question

I'm getting one extra file of type File on downloading attachments. I'm using MimeBodyPart.saveFile() here is my download attachment code

for (MimeBodyPart mbp : msgToDownload.getAttachmentList()) {
     updateProgress(msgToDownload.getAttachmentList().indexOf(mbp),
     msgToDownload.getAttachmentList().size());
     mbp.saveFile(DOWNLOAD_LOCATION + mbp.getFileName());
 }

here msgToDownload is a Class that take Message msg as parameter with some other parameters. And getAttachmentList() is a list of type MimeBodyPart defined as List<MimeBodyPart>
This is how I'm adding attachments to list

    sb.setLength(0);
        msgToRender.clearAttachments();
        Message msg = msgToRender.getMsgRef();
        try {
//            String messageType = msg.getContentType();

            sb.append(getText(msg));

            if (hasAttachments(msg)) {
                Multipart mp = (Multipart) msg.getContent();
                for (int i = mp.getCount() - 1; i >= 0; i--) {
                    BodyPart bp = mp.getBodyPart(i);

                    MimeBodyPart mbp = (MimeBodyPart) bp;
                    msgToRender.addAttachment(mbp);
                }
            }
    }catch(Exception e){
    }

Extra file contain attributes of text part of the Mail. Content of extra file

First, you should learn about the isMimeType method.

The problem is most likely that you're not handling multipart/alternative messages. See the sample code in the JavaMail FAQ .
