What Compare and Merge is
Compare and Merge is a Windows application for comparing text files and folders, locating character-level changes, and merging selected differences. Files or complete folders appear side by side, with an overview bar indicating where changes occur. Users can edit directly, trigger automatic re-comparison, and merge lines or larger blocks by clicking or dragging. Results can be printed or exported to HTML, with Unix and Mac line endings supported. For development workflows, the software provides command-line automation for continuous integration and validation, can ignore case or whitespace differences, and is described as integrating with version-control workflows. The Standard License costs $39.95 per computer as a one-time payment. A fully functional evaluation allows up to 50 file comparisons, but there is no free plan. Supported systems include Windows 11, 10, 8, 7, Vista, Windows on ARM, and Windows Server; macOS and Linux are not supported. TGRMN Software develops the application.
