KDiff3

KDiff3 is an easy to use and reliable application designed to assist you in comparing files' contents and discovering if there are any notable differences.

The program enables you to add up to three distinct files, of various formats. They are all loaded in the main window of Kdiff3 and displayed in parallel panes for a better view. The application performs a character-by-character analysis, so as to return reliable results.

The integrated editor enables you to quickly solve all merge conflicts, simplifying the choice over what information to keep or delete. After identifying the differences and similarities, the program allows you to join the compared documents in order to obtain a single file containing all the data from the three sources.

Moreover, Kdiff3 allows you to contrast several directories and find out whether they all have the same contents, which can prove particularly useful in the case of backup folders. This way, you can see which contains the newest data and decide which can be discarded. Similarly, the differences can printed for further analysis.

Another interesting feature of Kdiff3 is the fact that it integrates into your Windows context menu, so by simply right-clicking a file or folder, you can compare it to another one in just a few moves, saving you a lot of time.

The numerous customizable options make the differencing process very user-friendly, enabling you to select the preferred fonts and colors that emphasize conflicts or discrepancies. Color-codes can even show the newest file or a missing document in a directory. Kdiff3 can also ignore numbers, C++ comments and cases from the analysis, treating them as white space.

With Kdiff3, you can quickly and efficiently compare files and folders, instantly discovering which are identical, signaling the relevant differences and merging them so no data is lost.
