The folder diff utility on the other hand compares files in the selected folders and highlights which are identical and which differ.
Diffuse has been designed specifically for the comparison of code. It supports a couple dozen programming and scripting languages out of the box and uses syntax highlighting automatically when it recognizes a language. There does not appear to be an option to change the color coding though and some users may find the way things are displayed too colorful to be useful.
As you can see on the screenshot, there is color everywhere making it difficult to spot the differences at times. The program supports the merging of files and the editing of selected files as well. The free version of ExamDiff is available as a portable program and installer. It displays a prompt to pick two files on the system on start and displays them next to each other in the interface afterwards. Here it highlights all differences using colors to indicate added, deleted and changed lines.
A menu at the top enables you to jump to any difference spotted by it directly. Files can be edited directly in the program window and a Unix diff file can be saved as well using the files menu. KDiff3 displays a prompt on start that you use to load one, two or three files that you want to compare. The files are displayed next to each other in the interface afterwards and when you scroll, all of them do.
The program uses colors to indicate changes on either side. Plain black on white text indicates identical lines or characters while green, blue or red colors indicate that information are not available in all files. Besides options to compare files with each other, it is also possible to merge selected information in various ways.
It is for instance possible to prioritize information in one file or configure the program to resolve basic differences automatically to save time.
Meld requires that Python 2 is installed on the system. It ships with it and will install the components it requires unless you uncheck that option during installation. The software supports two- and three-way file comparisons, folder comparisons, and supports a version control view that you can make use of as well.
It highlights differences between loaded files directly and uses colors to visualize those in its interface. What sets it apart from the majority of comparable solutions is the fact that it visualizes how blocks relate to each other in both files. Merge supports the merging of files and a variety of other options such as tabs to load multiple comparisons at once.
Tkdiff is a graphical front end to the diff program. You can use it to load two files which it displays next to each other afterwards. Each difference is listed in a small menu at the top left corner which you can use to jump straight to it. Options are provided to edit files directly in the tkdiff interface and to change how things are displayed in it as well. It is for instance possible to disable the scrollbar synchronization or to mark the current diff. WinMerge has been around for a very long time.
The program is available as a portable version or installer for Windows. You can use it to compare two different files that you load into it. Differences are color coded and options are provided to edit files directly in the program window, or to use the merging tools to merge information from two files. The software supports a large number of comfortable features such as support for bookmarks, plugins, options to generate reports or change how information are displayed in the interface.
Tip : WinMerge is an official fork that is in active development. So which file comparison tool is right for you?
I cannot answer that but I can give you recommendations instead. The tool that impressed me the most is Meld. While it requires the installation of Python 2, it supports a lot of different features, is available cross-platform, and supports folder diff on top of all that.
Also, and that may be equally important, it is updated frequently. A lighter option to that is Kdiff3 which worked well during tests, and if you require binary comparison of files, you may want to check out Aptdif instead.
Now You : Use another tool to compare files? Feel free to share it with all of us in the comment section below. The link for Meld is broken. I have been using ExamDiff for years, but I would love to find one that could ignore certain column positions, i. Nice list, but would have been better to see more data points. For example, which of these support ignoring leading whitespace, or all whitespace? What about case insensitive diffs? Can you output a summary of the differences especially useful if doing directory comparisons?
How does the folder diff command differentiate uniqueness — by filename, filesize, filedate, or any combination of the three? Just a suggestion for next time. Very surprised that you have not included Beyond Compare from Scooter Software. I have used it for years and feel it is better than anything on your current list. I totally agree with you Ryan. This is where a diff tool comes in handy. It makes changes visible and helps you understand them.
In this article, we've compiled a short list that helps you get an overview of the best diff tools on Windows. Being free and open source , Meld is a very popular tool on Windows it's also available for Linux.
It supports three-way comparing and merging and lets you edit files directly from the comparison view. Apart from diffing files , Meld also supports comparison of folders. It goes well beyond pun intended diffing simple text and also allows comparing PDF, Excel and image files.
The "Pro" version also includes a solid three-way merge. Just like Beyond Compare, Araxis Merge supports more than just text and image files. It comes in standard and professional editions, and for people working on both Windows and macOS, it's good to know that a single license is valid for both platforms.
Another free and open source tool answers to the name of KDiff3. The project hasn't seen many updates in recent years though you may be able to find more recent releases through this page , but it remains a solid diff and merge tool that should satisfy basic needs. Much like Araxis, the DeltaWalker diff tool also lets you compare office files. If you're regularly performing comparisons on a folder basis, it's good to know that DeltaWalker shines with great performance in this area.
