    Very good tool IMHO: I have been using it for years, both as a visual diff and it integrates well as a 3 way merge tool for version control systems not just perforce, e.g. git , svn, bzr. Which is its primary purpose. AFAIK its QT based, only ugly if you think QT is. Default UI uses RedHat default laf, and Crystal icons from Everaldo

    Can not compare directories. Ugly as hell.

    Not just Windows. Multiple OS Support. Free & OSS except for the "Matlib" and/or "Simulink" diffs. Free version supports diff for: File, Folder, Archive, Image, GIT, SVN, (maybe more?)

    diffoscope tries to get to the bottom of what makes files or directories different. It will recursively unpack archives of many kinds and transform various binary formats into more human-readable form to compare them.
