From legal and publishing professionals to reviewers and editors, and from software engineers to web developers, they will all find Araxis Merge to be an excellent tool to compare, merge, and sync up to three files or folders at once. After analyzing the files or folders selected both quickly and accurately, the program will provide you with the tools you need to accept or discard all differences found, regardless of how insignificant they might be.

Araxis Merge will display all changes occurring between the documents selected either in a vertical or a horizontal array. Differences are clearly marked using color-based codes, boxes, and connecting lines, and all you have to do is click on the icons provided to complete the final version of your document. Changes can be replaced, inserted, or deleted on a one-by-one basis, or you can replace the entire content of any of the two or three files being compared with that of any of the others. When it comes to text comparison, the program supports not only text-based files such as HTML, TXT, or XML, but also binary files (EXE, DLL, WAV, MP3, etc.) and a number of image file formats for pixel-to-pixel comparison (GIF, JPG, JIF, etc.). Other formats are also supported, though they will need to go through a text conversion filter first. These formats include Microsoft Office and OpenDocument files, PDF, and various others, as long as they contain an ASCII, MBCS, or Unicode character encoding.

Folder comparison and synchronization is – together with its three-way visual comparison capabilities – one of the program’s main assets. It lets you compare, clean, and merge full directory trees in an efficient and convenient manner. It includes a byte-by-byte comparison algorithm to look for invisible changes in recordable discs and USB memories, and is capable of analyzing archive files (ZIP, TAR, and others) without extracting their contents. That same comparison at byte level will let you check and detect, on a pixel-by-pixel basis, any differences occurring between two apparently identical images.

The program produces excellent results, and its excellent interface design, together with its high level of usability, make the whole comparison and merging task a rewarding and hassle-free experience.
