Araxis Merge Preview is an excellent program to visually compare files, their combinations and uses in the Araxis folder synchronization.

The program is used to compare font codes, Web pages, text files, images and binary files.

You may revise and intervene in the codes, working with fonts hierarchies that files have.

To carry out a comparison you need to copy the text and paste it directly in the window by means of the interface it will say window to compare files.
