MergeDock Puts Text, Folder, Image, and Binary Diffs in One Mac App

Field notes

The app combines synchronized text panes, folder-tree filtering, image inspection, and binary comparison instead of separating those jobs across different utilities. Its image workflow names five modes—side-by-side, overlay, slider, blink, and difference—while folder operations distinguish modified, one-sided, identical, and type-mismatch items. The site also describes indexed viewing for very large files and explicit confirmation before copy or delete actions alter disk contents.
