public class TransferPacket
extends _05OutPacket

 send data packet
 If send basic info
     1. head
    2. unknown 8 byte
    3. session id, 4 byte
    4. unknownn 4 byte
    5. length of data behind, 2 byte, exclude packet tail, include this.
    6. unknown 2 byte, same with part 5?
    7. photo's md5
    8. file name's md5
    9. file length, 4 byte
     10. file name length , 2 byte
    11. file name
    12. unknown 8 byte
    13. tail

 传送数据包
 如果传送基本信息
 1. 头部
 2. 未知的8字节
 3. session id, 4字节
 4. 未知的4字节
 5. 后面的数据长度，2字节，不包括包尾，包括本身
 6. 未知2字节，和5相同？
 7. 图片的md5
 8. 文件名的md5
 9. 文件长度，4字节
 10. 文件名长度，2字节
 11. 文件名
 12. 未知的8字节
 13. 尾部
 

 If send data info
  1. head
 2. unknown 8 byte. If it's not the last fragment, its 0x1000000000000001, otherwise, random byte
 3. session id, 4 byte
 4. unknown 4 byte
 5. data fragment length, 2 byte
 6. data fragment
 7. packet tail

 如果传送数据信息
 1. 头部
 2. 未知的8字节，如果不是最后一个分片，则为，0x1000000000000001，如果是，则为随机字节
 3. session id, 4字节
 4. 未知的4字节
 5. 数据分片长度，2字节
 6. 数据分片
 7. 包尾
 
 If it's receiver, the packet is used to notice server to begin send face
 1 .head
 2. unknown 8 byte
 3. seesion id, 4 byte
 4. unknown 4 byte
 5. length of data behind, 2 byte
 6. 4 byte, all 0
 7. tail

 如果是接收方，则这个包用来通知服务器开始发送表情
 1. 头部
 2. 未知的8字节
 3. session id, 4字节
 4. 未知的4字节
 5. 后面的数据长度，2字节
 6. 4个字节，全0
 7. 尾部
 
 If it's the reply to file data from the receiver:
 1. head
 2. unknown 8 byte
 3. session ed, 4 byte
 4. unknown 4 byte
 5. length of data behind, 2 byte
 6. one byte, 0x02, so part 5 is often 0x0001
 7. tail

 如果是接收方对文件数据的回复，则为
 1. 头部
 2. 未知的8字节
 3. session id, 4字节
 4. 未知的4字节
 5. 后面的数据长度，2字节
 6. 一个字节，0x02，所以5一般是0x0001
 7. 尾部
