Over at Manageability, Carlos explains where Google’s desktop searching application finds the data it indexes. Turns out, there’s already a repository for the data that Microsoft collects — Google is just accessing it. That explains why Google searches files associated with Microsoft applications, and leads me to think that it will perhaps be a long time before they add support for data from other applications, and who knows when there will be a Mac version of Google Desktop. (I don’t think never is a bad bet.)
