Deleting a folder does not delete the contents of the folder. The contents of a deleted folder (projects or sub-folders) are moved to the immediate folder above in the folder hierarchy.
Admins can delete a folder within the Company folder that another admin created. Admins may need to coordinate with other Admins to keep folder and project access consistent. See About Folders in Analytics
To delete a folder
Click the … ellipsis icon in the top-right.
Select Delete folder.
A confirmation notification indicates that the folder was deleted.
