Facility to allow user view the job in Window Explorer folder

I am developing a CAD software using C++/CLI .Net framework 3.5. The files are saved usi开发者_C百科ng serializing the objects. How do I provide facility to allow user view the jobs in Window Explorer folder (Like done by AutoCad), where by user gets a chance to look inside the file in explorer itself without opening the file in the software.

You need to create a preview handler. This MSDN sample shows how to build one. But this requires Windows XP or newer OS.
