专 题：列出、改变目录
你可以使用DIR命令来列出目录。实际上，DIR并不是FTP规定的命令，但是标准的用户界面从操作系统借用了这个命令。
图2 显示了DIR命令的结果。最右边是文件或目录的名称，然后是文件日期和时间。然后是10位的文件属性。你可以通过"d"属性分别目录或文件。如果是"d",表示这是个目录。
改变目录你可以通过CD命令改变目录。和DOS命令的区别是它使用正斜杠。例如改变目录到 /developr/vb directory：
ftp> cd developr/vb 250 CWD command successful.
再次使用DIR命令，你可以获得文件列表。图3 显示了 DIR命令在ftp.microsoft.com的 /developr/vb 目录的执行结果。
