This section describes how to delete an unnecessary dtree.
If a snapshot exists in the namespace where the dtree to be deleted resides and the dtree is not empty, delete the namespace snapshot that protects the dtree or delete the directories and files in the dtree. If the recycle bin function is enabled for the namespace where the dtree to be deleted resides and the .recyclebininternal directory is generated, delete the .recyclebininternal directory when deleting the dtree.
You can also click More on the right of a desired dtree and select Delete.
