    As BC and unlike Meld, it align changes by adding lines, which is a key feature to visually compare code. Meld explicitly states it does not do that. kdiff3 also supports multiple platforms (as stated). Unfortunately, it does not support on-click line/block merging (merge from side to side visually) like Meld or BC.

    Who pays for software in 2023? Only iLuddites. This type of software is done. New “features” nowadays are merely capitalist job creation schemes. Failing attempts to justify still taking money for an abundant resource.

    It only compares two disks to each other. You cannnot compare just two files by choosing them by your own.
