r compares all files in all subfolders (recursive compare). Parameters are prefixed with either a forward slash ( / ) or dash ( - ) character. Use WinMerge only if you are running the ANSI version of WinMerge, typically installed only on Windows 9x and WME systems.Įntering the command with no parameters or pathnames simply opens the WinMerge window. Use WinMergeU if you are running the Unicode version of WinMerge, typically installed on recent Windows systems. Use one of these formats for the WinMerge command: Most of these parameters are intended for using WinMerge as an external compare application or starting a compare operation from a batch file. Portable version available from PortableApps.The WinMerge command line accepts several parameters in addition to the paths to compare.

OverallĬompact, snappy and dedicated tool that works well on its own and integrates with other stuff just as well. It is not critical (buttons to jump between differences help) but I think NetBeans has that nailed much better in its comparison interface that uses arrow-like markings to show were lines go, without inserting tons of blank space. With high number of differences it can really blow up total amount of lines. Lines only present in one file are blank lines in opposing file. The one thing I don’t particularly like is how file comparison creates too much whitespace. There are plenty of plugins and filters features (with regular expressions support) to pick:Īpp also has extensive command line interface and integrates with everything from Windows Explorer to SVN tools. Strong featuresĪside for core comparing function (which is not that hard to implement) WinMerge goes extra mile to allow to customize and tweak how comparisons work. Interface is multi-windowed and can hold multiple comparisons (file or folder either) at the same time. It is bit of file manager and sync tool, bit of text editor and a lot of text comparison. What it doesīasically app compares files or directories to precisely find differences and allow you to work with those conveniently. I wanted to recommend something free, light and convenient (instead of heavier stuff I use generally) and remembered WinMerge. One of those tasks you can’t expect human to do reliably (browsing several hundreds of files and thousand of lines – yeaaaah), but computers are wickedly good at. I have been hanging out in Theme Hybrid forums lately (it is research for new theme, not having fun solving obscure code puzzles, honestly! :) One of recent inquiries was how to determine if files were modified and what was changed.
