Razor syntax to open explorer window

Noob here:

I'd like to have clickable link in Razor to open an explorer window on client m开发者_开发知识库achine when passed the appropriate path. I'm new to the syntax (and limitations), but it's all internal, so I can resolve any security issues (if relevant).

Alternatively, advice on a (very) easy to install free control is also welcomed. :)

In IE6, you should be able to write <a href="file://c:\whatever>...</a>.
I don't think that will work on any other browser.
