Take control of your source code, web pages and other files with DiffMerge. Use it to compare, understand and combine different file versions. DiffMerge is highly useful for software developers, web designers and other professionals. The tight integration between folder and file comparison makes it easy to identify and review every change in every source file, even when comparing source hierarchies containing thousands of files. Whether you are working with multiple revisions of files or need to keep multiple folder hierarchies in sync, DiffMerge could help save time and reduce errors by helping you to work quickly and accurately.
