WinMerge

Free, open-source file and folder comparison tool for comparing code, tables, configuration files and text changes.

Details

WinMerge is a free, open-source file comparison and merging tool for Windows that compares differences between text files, code files and folders. Researchers can use it to check script changes, configuration file differences, JSON data differences and changes across versions of text.

Use cases: file comparison, folder comparison, code diff checks, configuration file comparison, text version comparison

Note: For comparing Word document versions, Word's built-in Compare feature is recommended; WinMerge is better for plain text, code and structured text files.
