Where do you get the idea that it was deleting files from?

This means that it found a file with zero size, so it dropped that file
from the list. It doesn't mean that it deleted the file from the disk.

This means that it dropped files from the list because there's no other
file in the list with the exact same file size. It doesn't mean that it
deleted any files from the disk.

This means that it's dropping files from the list because their first
few bytes are different. It doesn't mean that it's deleting files from
the disk.


I have used rdfind myself. It does not delete files unless you pass an
option telling it to.
