When you have no further use for a folder, you can delete it.
If you have enabled analytics on the folder, you must disable analytics separately. Otherwise, the associated analytics data remains on the SQL server. Folders that are linked to a case must be disabled for analytics before you delete the case.
You must have the Delete Folder permission to delete a folder.
To delete a folder
Choose one or more folders that you want to delete.
To select multiple adjacent folders, click the first folder, and then hold down the Shift key and click the last folder. To select nonadjacent folders, click the first folder, and then hold down the Ctrl key and click additional folders. To select all the folders, press Ctrl+A.
