I am trying to asign disk quota in my organisation as per te different units in my company. I want to know how can I set up a limit on the size by groups instead of users. foreg. I want to assign a limit of 30 gb to my accounting unit out of a 250 gb. I need to know if it is possible to do so by Group Policy. Thanks and Regards.

I hope you understand disk quotas are PER VOLUME (or partition), not per directory or folder.
