Right-click on any two files in Windows Explorer to diff them immediately. Rulesets and options provide for customized appearance and behavior. Identical feature set on Windows, OS X, and Linux. Comparing two or more different folders is supported. Meld allows users to compare two or three different folders for differences. But if a user wants to 'zoom in' and compare files contained in these folders, Meld gives you the ability to do so and launch file comparisons between files contained in different folders or in the same folder. This code compare tool free download is available as a trial. Other Platforms. The code comparing tools mentioned above works with multiple operating systems. However there are also tools that are operating system specific such as the code compare tool for Windows or code compare tools for Linux, Mac, or Android. Meld is a visual diff and merge tool targeted at developers. Meld helps you compare files, directories, and version controlled projects. It provides two- and three-way comparison of both files and directories, and has support for many popular version control systems. Meld helps you review code changes and understand patches.

The file comparison tools on this page are useful in a few ways. Firstly, they can tell you whether 2 files have identicalcontent or not. Secondly, they can also be used to pinpoint the exact differences between 2 files (especially ifthey are plain text files). Thirdly, for programmers, they can be used to create patch files that can beused to update one of those files to the other (useful for sending small updates to your end users withoutrequiring them to re-download everything).
Note for non-programmers: since you're probably just looking for something to tell you if 2 files arethe same, or to tell you the differences between 2 text files, just ignore any software below where I say thatthe tool is a binary diff or patch tool (ie, stuff like bsdiff and xdelta). Those are mostly meant for programmers.Also note that not all the utilities listed have a visual interface; some of them require you to use thecommand line, so if you're not comfortable with that, get a different one. (As far as possible, I've triedto note in my mini-review below if a particular program is command line based to make it easier for you,but if I miss something, and you find the program doesn't have a window for you to click on, just downloada different program. They're all free, after all.)

(They are also used for things likeversion control software.)In any case, bsdiff is known for its ability to create very small patch files. The program works on numeroussystems, including Linux, the BSDfamily, Windows and probably others. Source code is available.

If you need to compare two text files and get a report of which lines have changed, theGNU command line diff utilities can show you those differences. It is a standard part ofUnix-type systems (like Linuxand FreeBSD, etc),but if you have an operating system that does not come with a usefulfile or text comparison utility, you can get the source code for the program here. Note thatthe utilities are command line based, and come only in source form, so you have to compile them yourself.

DiffMerge allows you to visually compare and merge files by graphically showing you the differences between them. Intra-line highlighting of differencesis supported along with support for editing the files. You can also perform a side-by-side comparison of 2 folders; the folder diff facility will showyou the files that are only present in one folder as well as distinguish between those that are identical and those that are different. It's Merge facilityallows you to see the changes between 3 files, automatic merging when safe, and the ability to edit the resulting file. The programsupports international character encoding, and works on Windows, Mac OS X and Linux. The Windows version features Windows Explorer integration.
Diffuse can compare an arbitrary number of files side by side. You can manually correct the output so that the matching lines arealigned as well as edit the files directly from the utility. It can retrieve files from a variety ofsource code version control management systemsincluding Bazaar, CVS, SVN, Darcs, Git, Mercurial, Monotone, etc, for comparison and merging. Other features include syntaxhighlighting, Unicode (UTF-8) support, unlimited undo, etc. The program requires that you havePython and PyGTK installed.
