Unlock multiple folders/files
I deleted multiple folders and files from an external hard drive which is managed by Time Machine, but many remain because they are locked.
Is there a way to unlock them en masse?

Holding down the option key when emptying the Trash will ignore the lock, but you really can't delete Time Machine backups that way.
At this point you would just Erase the drive and start over.
