What ExamDiff Pro is
ExamDiff Pro is a Windows desktop application for comparing and merging files and directories. It compares text, binary files, and folders, showing changes at line, word, or character level. Code-oriented tools include customizable syntax highlighting, regular-expression support, fuzzy line matching, moved-block recognition, and a scope bar for navigating code sections. Built-in plug-ins handle Word, Excel, and PDF comparisons, while additional plug-ins cover PowerPoint conversions, archives, JSON, OpenDocument text, and remote files or directories. Windows Explorer integration can start comparisons from the shell. Users can save difference reports and create directory snapshots for later comparison or archiving. Standard Edition costs 37.99 USD as a one-time payment; Master Edition costs 54.99 USD as a one-time payment and adds two-way and three-way merging, synchronization, plug-ins, and SSH/SFTP comparison. A 30-day trial is available, but there is no free plan.
