飞信是中国移动的综合通信服务，可以实现电脑对电脑和电脑对手机的即时通信，随着移动用户的增加，它拥有了广泛的用户群，所以对飞信的文件传输及还原性能研究有一定的必要性。文章首先探讨了飞信软件在文件传输时的过程。其次，重点对飞信软件传输文件时的特征给予了分析和研究，针对现在一些主流文件的明文传输进行了分析，如PDF和DOC文件，并得到了传输特征。最后，基于分析得到的特征对飞信传输的文件实现数据还原，为数据恢复提供了新的研究思路。

Fetion, as an integrated communications service of China Mobile, can PC-To-PC and PC-To-Mobile communication. With the increasing number of China Mobile users, Fetion also has a great number of users too. So it is necessary to research the document transmission of Fetion. Firstly, the process of Fetion document transmission is discussed, then the authors focus on the features of the document transn~ission. By analysis on the plaintext transmission features of mainstream document, such as PDF and DOC file, their transmission features string is obtained. Finally, based on the obtained features string of file transmission, the data recovery of files transferred by Fetion is realized, thus providing a new research idea of certain software for data recovery.
