Giving User Permission to view 1 folder on an SBS 2003 Share

I am running an SBS 2003 Server with a shared drive which houses all our files, users authenticate to the server and are given access to the files they need.  There is one user that is going to be remotely accessing the server and needs permission to only one sub folder in order to open a QB Database and do work within it.  My question is what is the best practice under SBS 2003 to grant that 1 user permission to the sub folder and the files contained within without giving her access to any of the other files on that share?  Thanks in advance for the help!
