Jim Allchin blogs about changes to offline files in Vista and includes the great titbit of information that now, finally, the pc will only sync the files belonging to the user that is logging off so that the access denied message does not appear delaying the log off/shut down procedure.
Also, synchronisation is intelligent in that it will only sync changes to files as opposed to the whole file itself (if supported by the application) – this should help a couple of my clients who have issues with long synchronisation times on their pc.
It will be interesting to see if a new version of csccmd comes out with Vista, which includes all the extra switches that the xp version did not unless you requested the hotfix from Microsoft support.
See The Filing Cabinet for more information on these new features.
