I accidently dropped a file (moved it) into a shared Dropbox folder. I don't own this shared folder. So I subsequently deleted that file from the shared folder because this file has sensitive information that the admin should not see. But when I go to permanently delete that file, it says I need the admin of the shared folder to help. Is there a way to delete this file permanently without having the admin help? I am afraid if I ask for help, the admin may choose to undelete the file and view it.
