Here is how to remove the empty folders.
It is possible for existing empty folders to be deleted from ArchiveExplorer. This gives a better display for users.
The delete operation makes extensive use of the storage and directory databases and will have a major performance impact on the Storage Service computer. You are recommended to run the deletion at a time when there is no archiving.
To delete all empty folders:
1. Start the registry editor on the Storage Service computer.
2. Create a new DWORD entry called DeleteEmptyFolders under the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\KVS\Enterprise Vault\Storage
3. Give DeleteEmptyFolders a value of 1.
4. Restart the Storage Service.
When you restart the Storage Service, it searches for and deletes the empty folders in all archives. At the end of the search, the DeleteEmptyFolders is automatically reset to 0 to turn off this functionality.
Empty folders can still occur, either because the user has deleted all archived items from a folder, or because you are running storage expiry and all the items in a folder have expired and thus have been deleted. You can run this process periodically to clean up any empty folders that have occurred.
