Delete old TWRP backups

But I do like to look at the pictures I made and reminescence, so I’d rather have everything available.

TWRP doesn’t back those up (see the warning on screen when TWRP creates a backup, the forum guide to backing up with TWRP, or the TWRP FAQ), so that should be a separate question to whether or not you have any use for the old backups.
