An anonymous reader writes "Microsoft has set late 2006 as the deadline for shipping Longhorn, but to make that date, it had to delay the full implementation of WinFS, an ambitious file system geared at letting users search through all of their files at once. In this interview with Bill Gates [^], he provides a summary of why Microsoft decided to drop WinFS, saying: "WinFS, I'd be the first to say, is very ambitious. Nobody has ever brought together the world of documents, media and structured information in giving you one simple set of verbs that lets you richly find, move around and replicate those things." Meanwhile, MS Watch [^] has published Longhorn head-honcho Jim Allchin's memo on why some Longhorn features had to be axed."
