(following operations are suitable for windows XP. Please note the 
order of installation is important. Midorder can result failure in the
application)

1. install IIS 
Control Panel -> add or remove programs, choose  
add/remove windows components. In Windows Components Wizard window, 
check Internet Information Services and then follow the wizard.
(Windows XP CD or any disks contain I386 directory is needed.)

3.* install ASP.net Web Matrix
(This installation is optional. It is only useful if you want to 
modify or develop the source code by yourself. )
It can be downloaded here:
http://www.asp.net/webmatrix/

4.download and install "File Management" web application

(1) download file fileManagement.zip, unzip it to any directory,
e.g. C:\myWeb. A subdirectory named "fileManagement" will be created automatically.
In the following we willuse %unzippath% denote the unzip directory.
i.e. here %unzippath% = "C:\myWeb"

(2) modify the web.config file. You can find this file under 
%unzippath%\fileManagement. Open it using notepad. Modify the value of key 
"fileManagementRootPath" to %unzippath%\fileManagement\
e.g. 
find 
         <appSettings>
            <add key="fileManagementRootPath" value="E:\dotNetSpace\fileManagement\"/>
         </appSettings>

in the file web.config, change it to

         <appSettings>
            <add key="fileManagementRootPath" value="C:\myWeb\fileManagement\"/>
         </appSettings>

save the file and close it.

(3) Publish the web application
    In Control Panel-> Administrative Tools, find "Internet Information Services" icon.
    Double click it, find Internet Information Services -> Your Host name -> Web Sites
    -> Default Web Site.
    Right click Default Web Site, choose new->Virtual Directory
    follow the wizard, in Aliase field, give a name of the webside 
    (This name is used for access your website. e.g. type fileManagement here, your website
     can be accessed at http://localhost/fileManagement or http://yourhostIP/fileManagement)
    In directory fild, browse to directory %unzippath%\fileManagement\
    Following the wizard to finish

(4) After publishing, you can find a sub Web named fileManagement under Default Web Site
    right click fileManagement, choose Properties. In the file Properites window, in tab
    Virtual Directory, be sure both Read and Write boxes are checked.
    Under Documents tab, check Enable Default Document box, add "login.aspx" into default
    documents. Click ok to close it. 
    In IIS window, choose Default Web Site, stop and restart it.

Now you can access your web site at http://localhost/fileManagement on your local machine
or at http://yourhostIP//fileManagement from other computer.

Note:

1. If register or project creation function cannot work, it may becuase you didn't assign
NTFS permission to the web account in the file system. 
You can fix this by right click the fileManagement directory in Windows Explore, 
choose properties. In Security tab, add Everyone and allow full control. 

Note: this can be reduced to several accounts. But I haven't figured out which accounts are
associated with this. Only add Internet Guest Account is not enough.

If cannot find security tab in the properties window, go to Folder Options in 
Windows Explore -> Tools -> Folder Options. In View tab, scroll down to the bottom and
uncheck Use simple file sharing(Recommended). Click ok and reopen the properties window
of fileManagement directory, you will find the Security tab.

2. Only administrator has the right to create a project. Therefore, the create project 
button can only be seen when user login as an administrator.

3. Since the user accounts and projects infomation is stored in XML files, creating users
and projects can easily be done by directly modifying the XML files. However, this is not
recommended. Because it may result unexpected operation if the modification doesn't strictly
follow the XML schema. It is better to use the register and create function provided in 
the application.

4. You can also run the web application without IIS if it is not available on your computer and
if you have Web Matix installed. But in such a case, the application is running on a virtual
web server which is only accessible locally. That means your web cannot be accessed from other
computers. For more detail, please refer to Web Matrix guided tour.
