What would interest me is a listing of these files
(including their inodes (-i) too):

/home/richard/.local/share/Trash/expunged/73080846/
/home/richard/.local/share/Trash/expunged/73080846/grub2 problem-2018-02-13/
/home/richard/.local/share/Trash/expunged/73080846/grub2 problem-2018-02-13/grub2 problem-2018-02-13/

Cheers,
