摘 要
本文首先对软件同步系统进行了一些介绍，包括软件同步系统这个问题的提出,以及主要解决办法。接着就对软件同步系统中三个重要组成部分进行了分别的介绍，即文件监视的实现、注册表监视的实现、网络传输的实现。在文件监视中介绍了一些API函数，及具体实现过程；因为注册表监视用到的API函数与文件监视中用到的API函数基本一样，所以主要介绍了注册表的一些概念，及注册表监视的实现过程；最后介绍了网络中的一些概念，网络传输的具体实现过程，网络传输中用到了Delphi的TNMFTP控件，利用它实现了FTP客户端软件，用于下载FTP服务器端的软件，而FTP服务器使用了Microsoft Internet Information Server(IIS)4.0的FTP服务器，我们只需要把需要下载的文件放到它的目录下就可以了。

Abstract
First,we do some introduce of The synchro system of software,also include why the problem been questioned,and how to deal with the problem.then introduce the three important parts of The synchro system of software.that is the monitor moudle of file,the monitor moudle of register and internet transfer.In the moniter moudle of file,we introduce the function of API and how to come true it;Because the function of API used by the minitor moudle of file,we don’t introdue it again,we mainly introduce the procedure of how to come true it.In the end,we introdue something about how to come true the the moudle of internet transfer,In the moudle of internet transfer,we use the TNMFTP,to use it come true the FTP software in the customer,in the server,we use the FTP SERVER of Microsoft Internet Information Server(IIS)4.0,we only need to put the file which needed to be transform into his directory.
