What is WinFS
Not a file system but something..else

WinFS is not, contrary to what some say, a file system.
Instead, it's a SQL based layer that sits on top of NTFS. Simply put, NTFS is a terrific file system. But what it needs is a modern, state of the art way for people to organize their programs and data so that users aren't having to dig through gigabytes of data to find things.
It turns your local hard drives into one big SQL database (okay, that's a bit of an oversimplification but you get the idea). And if you have Microsoft's server on that has WinFS support, you could potentially be able to find data quickly across your enterprise.
WinFS is not currently available but is scheduled to be released sometime after Longhorn and be available for Windows XP as well.
