Mike Ricciuti at CNET – New Windows file system enters testing:
Microsoft on Monday posted the first test version of a new Windows file system well ahead of its expected debut.
The company made the test version of the file system, called WinFS, available to subscribers to its Microsoft Developer Network service. The test release was unexpected. Microsoft has repeatedly said that the WinFS code wouldn’t debut until sometime next year.
It’s there and according to the docs:
“WinFS” Beta 1 requires Microsoft Windows XP Professional or Windows XP Home Edition with Service Pack 2 (SP2) installed. “WinFS” Beta 1 will install on other editions of Windows XP such as Windows XP Tablet PC Edition and Windows XP Media Center Edition, but is only supported on Windows XP Professional or Windows XP Home Edition.
“WinFS” Beta 1 installations on Windows XP Home Edition only provide local access to “WinFS”. Remote access components of “WinFS” such as “WinFS” Sync are not supported when “WinFS” is installed on Windows XP Home Edition.
You also need the Beta 2 version of Microsoft .NET Framework 2.0.
