vypada to ze se asi neshodneme, ale to nevadi treba za dva roky o tom dame rec znovu 
WinFS je asi tak filesystem, asi jako Northwind, u neho jenom chybi plugin do Pruzkumnika 
Dival jsem se i na MSDN a tam to preci pisi jasne (dulezite podtrzeno):
File Promotion
Files are either in WinFS or not. Any item that has a file stream part can participate in promotion/demotion, which we more generally call
metadata handling. When WinFS promotes a file, it extracts the metadata from the known NTFS file content and adds the metadata to the WinFS data store.
The actual data stream of the file remains in the NTFS file system. You can then query WinFS regarding the metadata
as if the file natively resides within WinFS. WinFS also detects changes in the NTFS file and updates the metadata within the WinFS data store
