First thing in order to delete the folder you need to have Folder Admin or the Folder Editor role.
Follow the commands below to list the folders underneath a folder
gcloud resource-manager folders list --folder <Folder ID>gcloud resource-manager folders list --organization <Org ID>gcloud projects list --filter=" parent.id: <Parent folder ID/ Organization ID>Once you identified active resources connected to the folder then finally you can run the below command to delete the folder.
