@kocyunus Welcome to Community!!

Can you explain more about your process and what activities are you are using.
share your flow if possible if not share as a snap

@kocyunus,

You will have to merge all the files and then remove the duplicates because while merging you won’t be sure which could be the duplicate data until and unless you consolidate all files.
