When deleting folders, keep in mind these guidelines:
Only the folder is deleted
Dimensions and sub-folders are not deleted and are moved to the root of the Shared Library
If deleting a sub-folder, only the sub-folder is deleted—dimensions are not deleted, rather they are moved to the root folder
To delete only folders:
Right-click a folder and select Delete, Only Folder.
A confirmation dialog box is displayed.
Click Yes.
Click OK.
