You must be a Project Owner or an Administrator in order to Delete Projects.
Deleting Projects permanently deletes all files and folders within the Project and is an action that cannot be undone.
To Delete a Project, select the project in the Projects Dashboard and then select the Gear Icon on the far right of the panel.
You will be prompted to confirm you wish to permanently delete the entire project and all files and folders that live within the project, by entering DELETE in all caps.
