Free Software to Merge Two or More Text Input Files

kdiff3 is a software package intended to merge two or more files or directories. Not only is this useful for programmers and developers, but a line-by-line differential analysis provides an extra sense of functionality when comparing different sources. These disparities can then be printed out through the use of a highly intuitive Graphical User Interface (GUI). KTE4, Unix and Microsoft operating systems are currently supported although there is a newer version intended for Mac users.
