If duplicate files are cluttering your storage, compare how each finder searches and how much say you have before anything is removed. Match methods and scan locations show what can be checked; folder exclusions, file previews, and automatic selection help shape the review. Recycle Bin or Trash handling may matter if you want deleted files to remain recoverable. Platform coverage, free-plan availability, and paid-from pricing add practical constraints. Among the named options are dupeGuru, Folder Size, and AllDup. Consider which locations you need to scan and how you prefer to inspect potential matches before cleanup.
