WinMerge

WinMerge is an open-source comparison and merging tool for Windows. It displays differences between files and directories in a visual interface. It is intended for users who need to determine what changed between versions and combine those changes when appropriate.

The application provides side-by-side line comparisons and highlights differences within individual lines. A file map presents an overview of differences in a location pane, helping users see the broader structure of a comparison. Filename and line filtering can use regular expressions to focus attention on relevant content. WinMerge also includes a syntax-coloring editor and support for Unicode.

WinMerge integrates with Windows Shell, allowing its comparison functions to fit into the Windows file-management environment. It supports Visual SourceSafe integration for workflows that use that system. Its user interface is translated into several languages, making the tool usable in more than one language setting. These capabilities place it in the Developer Tools category as a utility for examining and merging file-based changes.

MirrorNest distributes the official Windows build directly from its own storage. Each mirrored build is scanned for malware before it is published. This gives Windows users a download source that is aligned with the original build while adding a stated scanning step before distribution.
