WinMerge: Compare the content of folders, subfolders, and files, find differences, and merge duplicate content

WinMerge is a practical and friendly comparison and merging software for files and folders that lets you easily find differences and synchronize folder contents.

In the main window you can see the merge content of the two selected folders, the comparison result and information about the contained files including their type and creation date. You can set WinMerge to compare the directories recursively using multiple factors like the file size, entire content and modification date.

You can navigate through the list of detected differences and move or copy a file or folder to and from a directory to conveniently sync the content of two different directories. It's also possible to rename, hide, or delete files.

The application provides an editor that enables you to quickly compare two files and edit their binary structure or text content. After they are analyzed, the content of the two selected files will be displayed in dedicated panels side by side so you can easily sport any existing differences.

It's also worth mentioning that WinMerge offers line numbering, automatic highlighting of detected differences, Unicode support, and Word wrap. Users can cpoy the syntax or manually edit it to sync the content, plus you can set the program to automatically create a backup of the original file.

Support is provided for archives, Visual SourceSafe and Rational ClearCase versioning systems, shell integration, folder backup, plugins, and there's a patch generator included, as well as a comparison report tool.
