文档介绍：摘要
网络硬盘(简称网盘),是一种可以用户基于互联网登录网站的进行信息数据上传、下载、共享等操作的信息数据存储空间。免费的网络硬盘的可用空间较少,一般对文件大小、下载速度、存放时间等限制;付费的网盘能提供大容量空间,文件大小、下载速度、存放时间及格式都不限制。电子邮箱所提供的附件功能是最早的网络硬盘,随着空间的增大,附件功能分立成网络硬盘。
同样是使用网页,FLEX技术实现网盘是在网页中加载用flex制作的上传控件,该控件能实现多文件上传,可以支持上传进度条显示,界面也非常漂亮,经过代码的优化速度非常稳定,虽然FLEX技术不支持断点续传,上传进度的显示也只能从客户端获取,防火墙等软件可能会影响到此控件,但它比较适用于一般文件的传送。
,采用FLEX技术实现客户端的控制。实现了包括文件夹的操作、文件的操作、用户的注册登录三个功能模块;通过文件夹功能模块,可以添加、删除、浏览、重命名、移动文件夹;通过文件功能模块,可以查看文件属性、上传、下载、删除文件;通过用户注册登录模块,可以实现用户的注册账号,修改密码,进行登录等功能。该系统具有具有一定的应用价值。

Abstract
work hard disk (. network plate), is one kind of data storage spaces where the user can register the website based on the to carry on operation ,such as uploading, downloading, sharing data and so on. The work hard disk's usable space are few, generally to limits document size, downloading speed, storage time and so on; The plate can provide the large capacity space, the document size, the downloading speed, the storage time and the form does not be limited. The email address provides the appendix function is the work hard disk, along with spatial enlargement, the appendix function establishes separately work hard disk.
Similarly uses the homepage, the FLEX technology realizes plate by loads the upload which in the homepage manufactures with flex to control, should control to be able to realize the multiple file uploads, may support the upload progress strip demonstration, the contact surface is also attractive, passes through the code the optimized speed to be stable, although the FLEX technology does not support the break point to continue the biography, the upload progress's demonstration also can only from the client side gain, softwares and so on firewall possibly affect to this controls, but it is quite suitable for mon document transmission.
This system uses the development languages to realize the server end control, uses the FLEX technology to realize the client side control. Realized three functional modu
