问题
First, sorry for my poor English...
I want to add a virtual folder to Windows Explorer using a Namespace Extension (NSE), and I want users to be able to open this virtual folder to explore some path (e.g., c:\test).
How can I do this using Delphi? Thanks.

The place to start is the MSDN documentation: Introduction to the Shell Namespace. Naturally this is written from a C++ perspective but it's not too hard to map that across to Delphi.
Another excellent resource for such tasks is Code Project. For example: The Complete Idiot's Guide to Writing Namespace Extensions - Part I by Mike Dunn. In fact this is just part of an excellent series of articles on shell extensions.
At present Delphi is a poor choice because it does not produce 64 bit executables. This means that your shell extension will not run on 64 bit Windows which is now a serious limitation.
With the recent release of Delphi XE2 this limitation has been removed. XE2 is capable of producing 64 bit executables and can therefore be used to produce 64 bit shell extensions.

Basically a shell extension is a COM object that implements a set of interfaces. Which interfaces needs to be implemented depends on the type of the extension (there are some used by any extension, of course). You can start reading here (you need some C -> Delphi translation, but when you start to work on such matters is better you get prepared to it), and then the reference is of course MSDN
