Before you choose

Check the payment model

A free plan is available with many tools on this list. Other tools combine a free plan with paid features, while a separate group offers a free trial instead.

Check the listed paid-from price when you need capabilities beyond a free plan.

Match your devices

Platform coverage differs across Windows, macOS, Linux, Android, iOS and API access. Choose a tool that supports the operating system or integration point where your files live.

Review scan locations

Compare the scan locations a tool accepts before you install it. Folder exclusions can keep selected paths outside a scan when you need narrower searches.

Compare match methods

Match methods determine how a finder identifies duplicates. File preview can help you inspect a candidate before taking action, so check whether the tool includes it.

Look at removal controls

Automatic selection can speed decisions about duplicate copies. Recycle Bin or Trash support provides a recovery route when a tool moves files instead of deleting them permanently.

Check open-source status

Open-source tools can suit readers who need code they can inspect or modify. Confirm the licence terms before changing or redistributing code.
