I was really happy to discover that KDiff3 was resurrected in 2018 after being unmaintained since 2014. While my favorite recursive dir/file comparison tool is WinMerge, that is Windows only.

KDiff3 was the next best option for Linux/Mac. It works quite well for comparing recursive dirs/files for large backups. You can do a quick compare (size only) or a full binary compare.

12/24 The installation doesn't run on my Win10 This program seemed fast at comparing in the past, but didn't have a menu tool to shift elements left or right. Perhaps this shines for long file comparison in speed. Perhaps there are other special features that I'm not seeing.

Simple and effective, if a bit outdated visually.

Those are all outdated links. You can get the URL for Linux/Win/Mac binary downloads from the README https://invent.kde.org/sdk/kdiff3

Much faster than Meld on Windows, good for working with SVN

ReviewJun 28, 2017

I have two CSV files that only differ in the date format: YYYY-MM-DD HH:MM:SS vs. M/D/YYYY HH:MM.

KDiff3 takes 25 seconds to compare these files and freezes. Bug filed at https://sourceforge.net/p/kdiff3/bugs/217/.

At least the authors of Kdiff don't go around spamming review sites with their shilling.

Developer last update (2014) ... v0.9.98 (2014-07-04) ... at ... http://kdiff3.sourceforge.net/
AlternativeTo app page (2017) ... latest update was made in Feb 2017 ... ?

Developer's update (2014) is well after Kissaki's comment below , so there is a possibility kfiff3 is fixed
I would like to know if Kissaki's concerns have been addressed by the developer?
This is my first venture into text comparison, so I am a bit nervous at the reliability of kdiff3

What is KDiff3?

KDiff3 is a file and directory diff and merge tool which

  • compares and merges two or three text input files or directories,
  • shows the differences line by line and character by character(!),
  • provides an automatic merge-facility,
  • has an editor for comfortable solving of merge-conflicts,
  • provides network transparency via KIO,
  • has options to highlight or hide changes in white-space or comments,
  • supports Unicode, UTF-8 and other file encodings,
  • prints differences,
  • supports version control keyword and history merging.

History

KDiff3 was originally authored and maintained by Joachim Eibl through 2014. Then in 2018, it was ported to KF5/Qt5 by Michael Reeves, and actively maintained since.
