If you have the daunting task of picking out duplicate files from gigabytes worth of data, you’re going to need a duplicate file finder utility. The software will also effectively function as a duplicate file remover, so let’s look at a few options for both Mac and PC.
Duplicate File Finder – Mac
- Singlemizerapp is a paid app (the free trial will not allow you to remove duplicates). It features a nice step by step process whereby it scans your internal or external hard drives and lets you double check the flagged duplicates before deleting them.
- Grupadupa is simple – its default search is just to search duplicates by filename which should be good enough for most situations. You can alter its search behavior via its preferences to also check for filesizes. Grupadupa is freeware.
Duplicate File Finder – Windows
- Anti-Twin is a freeware app for Windows that has been praised for its heuristic approach to file matches. If you have lots of files that are slightly different from each other (as in slight variations in how they’re named) then Anti-Twin will be a good option.
- Anti-Twin was also featured on this roundup, so there’s other options if it doesn’t quite do what you want.
