When you delete a folder, the deletion typically cascades to the folder contents too. All subfolders and documents that are visible to you are deleted along with the folder.
Any items that you do not have permission to see are hidden from deletion. The folder and all items that are visible to you will be deleted, but any items that are not visible to you will not be deleted. If the hidden items were filed only in the folder you deleted, the items become unfiled, which means they are not in a folder and they are accessible only through searching or by browsing in the All ItemTypes library.
When you delete a folder, the folder contents will be deleted even if they were multi-filed, which means they were filed in multiple folders. The items are deleted and removed from all multi-filed locations. For IBM® CMIS, the deleteSingleFiled option deletes all non-folder objects that can be filed whose only parent-folders are in the current folder tree. The option will unfile all other document or non-folder objects that can be filed from the current folder tree. Use the folderTreeDeleteOptionSingleFiledOnly configuration setting to mitigate the limitations of the cascade delete feature of Content Manager EE.
Most applications request cascade deletion by default. Depending on the service interfaces that are used by the applications, some applications specify an option to indicate cascade deletion, whether presented to the user or assumed as application behavior.
