Application to compare files and folders to find differences, code changes, updates and duplicate content.

WinMerge is a free and open source tool for comparing files and folders and then merging the contents of them. Its utility is useful not just for programmers but also for writers.

Unlike several other tools which specialize in just comparing sets of files, WinMerge can also deal with directories and merge the contents of them. This can be useful for photographers who have collections of photos across hard drives.

The program has many useful features and supports different operations such as rename, move, copy, archive (as zip files) and deletion. Customization of WinMerge can be accomplished easily; users may change colors and other visual elements.

Overall, the user interface of WinMerge is well done and user-friendly. Its various features and options make it a perfect tool for many different sets of users from photographers to programmers alike.
