How does the Snipping Tool in win7 persist it's "Save As" path?

Question

It doesn't store it in the registry or a file.

It seems like it must persist the default path using the "Common Item Dialog", but how do can I find the actual path knowing this? It seems like the info is supposed to be private to the app...(?)

Oddly, I don't even see msdn info about how to access the "Common Item Dialog" from dotnet, so I really need to go through all the interop hassle myself?

Then it's unclear how I'd obtain the GUID that Snipping Tool is using, so I can do things like: GUID guid; pfd->IdentifyDialog(&guid);
