ProjectDiff is a Windows desktop tool from Foo Software, positioned as software for comparing, merging, and synchronizing projects, folders, text files, and hexadecimal files. It is aimed at software developers, web designers, and professional users who need to manage multi-version file hierarchies, with an emphasis on quickly identifying changes in source code or website directories containing large numbers of files and reducing manual merge errors.
Its standout feature is integrated “project–folder–file” comparison. At the project level, it supports project formats such as Visual Studio, Visual C++, eMbedded Visual C++, Visual Basic, Visual J++, Borland Delphi, and C++Builder. At the folder level, it can compare by modification time, size, attributes, version, CRC, binary content, or text content, and perform synchronization operations such as copy, move, delete, rename, and changing timestamps and attributes. Text comparison supports ASCII, MBCS, and Unicode, offering side-by-side color-coded differences, inline highlighting, syntax highlighting, a built-in editor, unlimited undo, search and replace, and regex support. It can also ignore whitespace, comments, case, line endings, and lines matching regular expressions, making it suitable for filtering timestamps or version-control keywords. Hex mode supports byte-level comparison and merging.
The official website states that users can start a free 30-day trial and provides a Purchase entry point, but it does not disclose specific pricing, licensing terms, or payment methods. For enterprise procurement, pricing transparency is limited, so buyers will need to contact sales or proceed to the purchase page for confirmation.
Its strengths are its comprehensive feature coverage, detailed folder synchronization and text merge rules, and HTML reports with syntax highlighting, which are convenient for archiving and distribution. Windows Shell extension support and drag-and-drop also lower the barrier for everyday use. The drawbacks are that it clearly supports only Windows, with no mention of integration with modern development workflows such as Git/SVN, CI/CD, command-line tools, or APIs/SDKs. Its supported project formats also skew toward traditional environments, making it less appealing for modern cross-platform development ecosystems.
It is suitable for individual developers or small teams maintaining legacy Windows, Delphi, C++, or Visual Studio projects who need offline folder synchronization and fine-grained text merging. If a team depends on cloud collaboration, automated pipelines, or cross-platform tools, Beyond Compare, WinMerge, Meld, and similar alternatives may be more appropriate.
