Archive Folder and Item Counts

Hi,
I'm looking for a way to display some archive information. I'd like to report on folders and the count of items in each.
I have the below to list the folders, which table/tables can I link to get an item count?

USE EnterpriseVaultDirectory
SELECT * from ArchiveFolderView
WHERE ArchiveVEID = 'UserArchiveID'

I'm guessing RootIdentity or VaultEntryID from the above can be used to join with another table and return a count?
Any help would be greatly appreciated.
Thanks
