Platform coverage, free-plan availability, and paid-from pricing offer further points of comparison. dupeGuru and Duplicate Cleaner are among the options, as are Czkawka and fclones. Recycle Bin or Trash handling may matter if you want deleted files to remain recoverable. Weigh these details against the locations you need to scan and how much say you want in deciding which matches to remove.
