Migrating directories with JavaScript

Javascript

These two days with virtual machine installation system, ready to use virtual machine to separate development environment and database, the idea is as follows:
1. Development environment for host
2.Guest is a database server, each server is a stand-alone virtual machine
Database includes Oracle 9i, SQL Server 2005, MySQL

But install the system, but also set the environment variables to reduce the system disk occupancy and increase performance, which requires the migration of some directories of the system disk, such as IE temporary directory, temporary folder, Applocation Data; In addition, we also need to move important folders to other partitions, To avoid critical data (MyDocument, Favorites, program configuration, etc.) that are not affected when the system disk crashes or wants to recover.
Manually modifying environment variables and registry values too troublesome, because every time I install the system to be modified so once, this time is enough, in the heart a ruthless. Okay, I'll write a script to get you out!
BAT is not allowed to set system environment variables, and in addition, VBScript and JScript are available; The advantage of VBScript is that there is a dialog box, JScript is not (alert, etc. can only be used in a Web page), and JScript's code is clear and powerful, and you can use features such as regular expressions.
So, write the following script, everybody prawns please look at the code:

Which profile for valuable data and documents, Volatileprofile used but no value of data and documents. In this way, we can clearly know that profile to retain, volatileprofile can be often cleaned up.

I also need to migrate the Desktop,my document,favorites folder to the profile directory and then start installing the database.
But, today is too late, tomorrow again ~ ~ ~
Use the JScript operation registry tomorrow to migrate some directories of the system to the profile and Volatileprofile directories.
