今天看了一下ccopus的DM45，做的很不错，在这之前我也想做一个了，做一个跟windows资源管理器非常类似的程序。看到dm45以后觉得自己还是放弃吧，WEB方式的文件管理无论如何都是在权限允许内操作，而且大家实现的也都差不多，无非是在外观上，易操作上做文章，文件管理本来作用也不是很大，如果是多用户的权限比较难控制，既然别人做了，我想还是不要重复劳动的好，况且也不见得能做的好。下面的代码贴出来留个纪念，实现了文件的本地排序。但目录之间的层次还没有搞好。有兴趣的可以拿去参考，理论上应该可以实现跟windows资源管理器极类似的界面和操作方式。整个界面都采取无刷新方式。用XMLHTTP来执行后台代码，用JS来修改前台显示。这里体现了一种思想，希望对初学者能有个帮助。
代码如下：
