Shared Folders – limit folder size

Hi,
Is it possible to limit the size of a folder within a shared folder on a Windows Server 2003 Server? Currently there is a shared folder called ‘Shared’ and within that, there is a folder for each employee within the company, (e.g. Shared:\emp1, Shared:\emp2, etc.) I want to set a maximum folder size for each of these folders, (ideally, I would like to set different limits on these folders.)

Is it possible to do this, (I know that you can set a maximum for the ‘Shared’ folder, but what about the folders nested inside?
