How to Set Up the Minimal File Size in Duplicate File Finder

Duplicate File Finder is a really fast duplicate searcher for Mac. The application allows you to find any type of duplicate files: images, videos, music,  documents and so on. It takes less than a minute to scan your folders and find duplicates in them.

Duplicate File Finder provides a wide set of features to make the search process simple and fast. For example, you can set up the file size threshold to be searched. This is a useful option when you want to preview only the biggest duplicates to quickly free up some space on your drive. Read on to learn how to change the size of duplicate files to be scanned.

Note, by default, Duplicate File Finder finds duplicates by skipping the smallest files. That’s done to give it better performance especially when it’s scanning huge and slow external drives. However, this behavior can be changed using the app’s preferences.

To change this option, open the Preferences and go to the Scan tab.

Here you will see three options for the file size filter:

  • Automatically define the minimal file size for better performance. With this mode, the app detects automatically what size of duplicates files to search to give you the best performance.

Please note that if you use the automatic mode, you may face a situation when, after each time you search and delete duplicates from the same drive, it finds several more smaller duplicates. However, it doesn’t show all of them the first time. The minimal file size threshold can therefore be reduced since the last scan, and some new duplicates can be displayed. If it happens, you will see the appropriate message on the app’s window.

  • Scan all the files (takes more time to scan)

In this case, the application will scan and compare absolutely every file on your drive, even the smallest. As a result, it might take more time to scan your folders.

  • Manually set up minimal file size

Enable this option if you want to change the size threshold of files to be scanned by Duplicate File Finder. Just move the reflection on the slider and set the size you need, from All Files to file size 10 MB, for example. This option is especially useful when you scan large storages with a large number of small files and want to find only bigger duplicate files. For example, if you set up the slider at 1 MB, the Duplicate File Finder will skip all files smaller than 1 MB and show you only big duplicate files.

Conclusion

For your convenience in most cases, we recommend that you use the automatic mode of defining the minimal file size. However, it’s your choice and you can change the Preferences to suit your needs. For example, if you want to get rid of absolutely all duplicate files on your dive, you should use “No minimal file size” option so that to scan all files. When you have a large storage with thousands of small files, use the “Manual” mode to set up the size of files to be scanned. And finally, if you scan your Home folder and need just to quickly free up some space, the automatic mode will provide the best performance of the duplicates search process.
