Beyond Compare is a data comparison utility. Aside from comparing files, the program is capable of doing side-by-side comparison of directories, FTP and SFTP directories, Dropbox directories, Amazon S3 directories, and archives. It is available for Windows, Mac OS, and Linux operating systems.
The GUI is written using AutoIt v3.1.0 - this is NOT required for the plugin to run.
All files (over and above those on the original Windows CD) are contained in the plugin - no additional downloads required.
