摘 要
本程序主要用于简单服务器的管理，包括文件的上传、下载、列出目录、改变目录、改变传输方式等功能。通过该程序的开发，基本上实现了一个FTP服务器的功能，能够解释一般的FTP命令，并且符合RFC959规范。
本程序采用VC 6.0作为开发工具，设计步骤采用自顶向下的。
关键词：上传、下载、列出目录、改变目录、改变传输方式、FTP服务器
引 言
从根本上说，FTP就是在中各种不同的机之间按照TCP/IP协议来传输文件。FTP采用的是现在流行的Client/Server模式，由FTP客户端和FTP服务器端程序组成。通常服务器端是远程端点，用户可以通过Internet网络连接到远程的FTP服务器站点。服务器的功能是主要的。只有当FTP服务器支持各种协议和指令时，才能够开发相应的客户端程序。
本程序支持最基本的FTP命令。现归纳本程序的特点如下：
