"WinFS" is the code name for the next generation storage platform in Windows "Longhorn." Taking advantage of database technologies, Microsoft is advancing the file system into an integrated store for file data, relational data, and XML data. Windows users will have intuitive new ways to find, relate, and act on their information, regardless of what application creates the data. Also, "WinFS" will have built-in support for multi-master data synchronization across other Longhorn machines and other data sources. The platform supports rich managed Longhorn APIs as well as Win32 APIs.
