CMS?

Hi there! Anyone know a good CMS for handling documents and adding/deleting news in diffrent categorys. Mambo/Joomla or Sharepoint Server would be great, BUT in these systems documents are stored in ONE map on the server (and through the db - the site shows respective document is shown in diffrent categories).. But I'm looking for a CMS that stores documents in physical paths, like this... Category Cars -file1.jpg Boats -file2.doc -file3.doc Buses -file4.doc In for example this files are stored like this: mambodocuments/file1.jpg, file2.jpg, file2.jpg, file3, file4.jpg I want the CMS to store the files like this mambodocuments/cars/file1.jpg mambodocuments/boats/file2.jpg mambodocuments/boats/file3.jpg mambodocuments/buses/file4.jpg Anyone? Help :-) Best regards /Gustav Wiberg
