CSDiff

ComponentSoftware Diff (CSDiff) is a powerful, free file-difference analysis tool designed for Microsoft Windows. It's an essential asset to anyone needing to analyze changes made between two versions of the same file or folder. It's commonly used for program source files, MS-Word documents, and HTML documents, making it an indispensable utility for developers, content writers, and designers.

One of the key features of CSDiff is its powerful folder and single-file comparison tools. The single-screen display provides an intuitive difference analysis, which is ideal for printing or creating reports. With the edit mode, changes can be accepted, rejected, or manually edited. Additionally, change detection can be done by line, by word, or by character, providing greater granularity in analysis.

CSDiff also features a smart white-space difference analysis option and a sophisticated folder difference analysis sorted by any key. Furthermore, CSDiff supports compressed folders (ZIP files), allowing for comparison between archived folders and regular folders. And its enhanced folder difference analysis reports, including HTML and XML reports, filters, and links to file-level analysis, provide unparalleled reporting capabilities.

The newest version of CSDiff (version 5.0) boasts several new features, including support for compressed folders for comparison between archived and regular folders, review mode output file editing, and improved accuracy. Additionally, version 5.0 also addresses a bug in the report command for folder analysis, among other fixes.

Overall, CSDiff is an excellent file-difference analysis tool that does exactly what it says on the tin. And with its freeware license, it can be used completely free of charge. If you need the ability to analyze changes between two revisions of your files or folders, CSDiff should be at the top of your list.
