Like the Nektony Duplicate File Finder, this tool also has an Auto-Select feature. Unlike the former, however, Cisdem gives you the option to see how the process is going in real-time.

Automatically, this tool will also mark multiple duplicates in red, so you’ll know which to get rid of. To further reduce the friction of deleting useless files, you can also sort everything based on the date stamp. Say you’re aware that there will be multiples of each file from your most recent folders; you can just choose to “Keep the Oldest or Newest File in the Group.”

Sometimes, you might just want to sort through duplicate files. Maybe even filter which of the files you can still use in the future. In this case, you’ll definitely appreciate the app’s Recycle feature.
