Finding a source in a complex project in VS2008

I've inherited a huge .NET project to maintain, with each project tree MANY levels deep,
in Visual Studio 2008.

Is there a simple way to search the Solution Explorer to find in which node a particular
source file is located, so I can check it out through VS2008?

Obvious I do NOT want to manually expand each node
and I'd like to avoid having to examine the XML of the .vcproj file.

Thanks

Using windows explorer search feature from the root directory of your solution.
