How does the tool for removing duplicate domains in the list of links work? If I check all types, does it remove duplicate domains in each file individually or in all files at the same time? If the domain is in the file with articles, will it be deleted in the file with comments or not?

GSA connoisseurs? Tell me, are links from the site_list-identified folder checked and deleted from there
