　FreeFileSync是一个易于使用的开放源码文件夹同步和比较软件，简单易用。 FreeFileSync[1] 首先是文件同步功能，可以在指定的两个文件夹之间进行单向或双向的同步，点击程序窗口右上方的绿色齿轮图标可以设置相关参数；期间也可以自定义需要筛选的文件，有“包括”和“例外”两种过滤方式，定义需要过滤的文件类型，这就看个人需要了。(FreeFileSync is an easy to use open source software folder synchronization and comparison, easy to use. FreeFileSync [1] The first is file synchronization, you can specify the folder between the two one-way or two-way synchronization, click the program icon in the window at the top right of the green gear can set parameters period can also be customized to sift through the file, the " include" and " exceptional" two filtering methods, definitions need to filter the file types, which depends on personal needs.)

说明：  在Internet上的聊天室程序一般都是以服务器提供服务端连接响应，使用者通过客户端程序登录到服务器，就可以与登录在同一服务器上的用户交谈，这是一个面向连接的通信过程。因此，程序要在TCP/IP环境下，实现服务器端和客户端两部分程序。(In Internet chat rooms on the procedure is generally based on the server side connection in response to the provision of services, the user through the client program to log on to the server, you can log in the same server with the user to chat, this is a connection-oriented communication process. Therefore, procedures to TCP/IP environment, the realization of server-side and client procedures in two parts.)
