Learn how to – Find File Duplicates on Linux/macOS/Windows using dupeGuru.

Having a “disk full” error is one of often errors faced by individuals. This error may result from having duplicate files on your system. Saving these files may happen knowingly or unknowingly for example downloading a file twice in the same or different directories. This may lead to the disk full error that may baffle you from storing other important files.

Tracing file duplicates can be extremely hard. No matter how organized your system is the file duplicate can be buried in your system and make it so hard to trace it. An easy way to identify these duplicate files is by using dupeGuru. This is a free and open-source cross-platform tool written in Python 3 that lets you quickly identify file duplicates on your system. It scans the filenames or contents and features a fuzzy matching algorithm that identifies the duplicate even when names aren’t exactly the same.

It supports several languages such as English, German, French, Chinese (Simplified), Czech, Vietnamese, Italian, Ukrainian, Brazilian, Armenian, and Russian.
