NextDiff
NextDiff is a free Windows utility for comparing files and folders in a clear visual interface. It helps users inspect differences between two versions of a text file, source code file, log, script, or configuration file. The side-by-side comparison view highlights added, removed, and changed lines, while in-line change marking helps identify the exact modified fragments. NextDiff also supports folder comparison, direct editing, copy-left/copy-right merge actions, difference navigation, and flexible options for ignoring case, blank lines, and whitespace. It is a useful freeware tool for developers, administrators, writers, and anyone who regularly works with changed files.
