UltraCompare Professional is a powerful compare/merge application loaded with features to enable users to track differences between files, directories, and .zip archives! File Compare features include text and binary compare of two or three files at a time and users can merge differences between compared files. Folder Compare supports comparison of local/network directories (and subdirectories with recursive compare) and .zip archives as well and users may merge differences between them. With automatic integration with UltraEdit-32 or UEStudio, UltraCompare Professional is a tool no user should be without!
