Beyond Compare is a file comparison program.

Beyond Compare is used by developers to compare software source files.

Beyond Compare lets you compare files and folders quickly and easily. With simple, powerful features, you can focus on the differences you're interested in and ignore the unimportant ones. You can then merge changes, sync files, and generate reports.

You can compare entire disks and folders at high speed, checking only the size and modification times, or you can test thoroughly, comparing each file byte by byte. FTP sites and zip files are integrated seamlessly, so you can update your website with a single click.

Once changed files are found, Beyond Compare intelligently chooses the best way to compare them and show the differences. Files can be viewed and edited with syntax highlighting and comparison rules tailored specifically for the document type, source code, and HTML. Text content of Microsoft Word .doc and Adobe .pdf files can be compared but not edited. Data files, executables, binary data, and images have dedicated viewers , so you always see changes in the right view.
