What is Duplicate File Finder?

A duplicate file finder is a tool that simplifies finding and removing duplicate items from your computer. These apps allow you to pick the locations to scan and identify duplicates and items they see as similar. Thanks to this, you can select the files for deletion easily and prevent cluttering your computer with unnecessary files.

Duplicate file finders can be simple tools that only look for identical file names. However, the best apps out there can also search for similarities and provides additional functions to give the user total control over the deletion process.

Who Should (Or Should Not) Get A Duplicate File Finder?

Duplicate files are a common problem for computer users. You might have saved different versions of the same document, and ended up with several variations you don’t need. If you love taking photos, the odds are you have numerous similar ones stored. Additionally, if you have been using the same machine for years, at least a couple of duplicates must have appeared along the way.

That is when you might need the best duplicate file finder out there. Here are the situations when you can utilize these programs:

  • You are low on disk space and need to free up some room on your hard drive
  • You noticed numerous duplicates on your machine
  • You have thousands of photos transferred to your device, but they are not organized
  • You synchronize your PC and mobile phone or another portable device often

If you have a brand-new computer, you might not need these tools. But after a while, it becomes a crucial asset in managing your machine.

How We Test the Best Duplicate File Finder for Windows/Mac?

We took the search for the best-rated duplicate fie finder software seriously. Our team made sure to analyze all relevant features, including the ones listed below.


The tool must be compatible with your operating system version to work. Duplicate file finders might come in versions for Windows and Mac. Additionally, you want to ensure they support your machine’s OS. Some programs might work on Windows Vista, but don’t support Windows XP. Others might not be compatible with the latest macOS versions. That is why it is important to confirm the compatibility of the tool with your PC.

Search Options

The basic search option is to look for files with identical names. That is what even the simplest duplicate finders do. However, the best tools out there will provide multiple options for customizing the search process. You should be able to search for specific tags, look for similar files and content, and utilize other parameters to narrow down the search.

Scanning Speed and Reliability

You want the scanning process to go fast. While that always depends on the quantity of data to analyze, these tools will usually scan the system quickly.

Apart from speed, reliability is also important. The duplicate finder needs to follow your instructions. If you exclude certain folders from the search, they shouldn’t appear in the results. That is why you should only pick software capable of delivering detailed results based on your instructions.

Intuitive Interface and Customization Options

The developers need to make their software simple to use for beginners. However, a high level of customization is something that advanced users need. An intuitive interface will allow you to browse the scanned files and select the ones to remove. Sorting files by type, name, or group is also a convenient feature.

If you delete a file and realize you need it, some duplicate finders also offer the restore function. Others will only move the items to the Recycle Bin so that you can restore them if necessary.
