As test versions of the new WinFS file system were released this week, Microsoft said the technology would not be ready for the so-called "Longhorn Server" release, due in 2007. While the company announced almost a year ago it was dropping WinFS from the desktop Vista release, Iain McDonald, director of Windows Server Group, has confirmed the file system will not ship with the server release scheduled for 2007, despite earlier promises it would be.
"It just wasn't ready. It will release but we're much better off taking a slow burn approach rather than forcing it to change the world on day one," McDonald told Builder AU in an interview at the TechEd conference in Queensland.
cool down dude.
