Beyond Compare is a file comparison tool that can quickly compare the differences between folders and compare the differences between files in detail, and mark the differences in color. The program has a built-in file browser, which makes it easy for you to compare differences between files, folders, compressed packages, FTP websites, and synchronize data. You can use it to manage program source code, synchronize folders, compare program output, and verify CD copying. It also supports script processing and plug-ins, especially for Chinese support.
