ScooterMcGoo writes "According to a Microsoft Watch blog, WinFS is being back ported for Windows XP. From TFA: WinFS isn't dead, Tom Rizzo, Microsoft's director of product management for SQL Server, recently told Microsoft Watch. In fact, Microsoft is planning to provide an update on the technology at this year's Professional Developers Conference (PDC) in September, he said. Rizzo said that Microsoft is busily back-porting the WinFS file-system technology to Windows XP. It's unclear if Microsoft also is porting WinFS to Windows Server 2003, but such a move would be likely, given that the Redmond software vendor is doing so with Avalon and Indigo."
