Offline Files issue - Please help

I would like to setup Offline File synchronization so that
my mobile users can have their user files on the server
cached on their hard disk. I am using a Group Policy to
do this. I would like just the user's files in his/her
user share to be synchronized. However, I am not able to
find a way to limit this just to the users' shares. It
seems to synchronize everything that is in the users root
directory that a user has opened. Is there a way to
exclude other files and limit synchronization just to the
specific user folder?
