Beyond Compare

With Beyond Compare, use simple commands to quickly and easily compare your files and folders, focusing on the differences you're interested in and ignoring those you're not. Merge changes, synchronize files, or generate reports for your records. Compare entire drives and folders at high speed, or thoroughly verify every file with byte-by-byte comparisons. FTP sites and zip files are integrated seamlessly, so you can update your website with the touch of a button. Comparison rules can be tweaked specifically for documents, source code, and HTML, with dedicated viewers for data files, executables, binary data, and images as well.
