How to get folder structure including items from list, without using webservices

Question

I have a list containing folders and items. The folders are a custom content type based on folders, with some extra columns like URL and some Yes/No Checks. One contenttype can contain n items and contenttypes.

So lets say I have this structure:

FolderA
   ItemA.1
   FolderA.2
      ItemA.2.1
      ItemA.2.2
   FolderA.3
FolderB
  ItemB.1
  ItemB.2

How can I get this structure without using the list-webservice? I know how to get all items in the list, but that returns only items, not the content types. It's also (in my opinion) no good way to do a single query against each folder because the list will get very large.

Thank you very much!
