Everyone has duplicate files on their Windows computers. After years of use, it’s almost impossible to avoid. Some of those dupes, however, might be very large files that needlessly waste disk space and might cause you to replace your computer sooner than necessary.
dupeGuru is a great application for this. It’s completely free and comes in three flavors: dupeGuru, dupeGuru Music Edition, and dupeGuru Pictures Edition. The music and pictures editions are specialized for finding similar music files and pictures. For example, the music edition will find the same song, even if they’re in different MP3 files encoded at different bitrates. Or the pictures edition will find copies of the same photo even if they’ve been resized, rotated, or slightly edited. This utility uses a “fuzzy match” algorithm and can find files that are very similar and not just completely identical.
Once dupeGuru finds the duplicates, you can do whatever you want with them. Not only can you delete duplicates, but you can also move or copy them elsewhere. There are also multiple ways to filter and sort your results to easily weed out false duplicates (for low threshold scans). Download your free copy of of dupeGuru here. On the same web page there is a nice, short video that shows you how to use it. Enjoy.
