The comparison map shows the positions of the blocks in the files being compared, and how they correspond.
There are three types of blocks:
- Matching (identical) blocks are shown in green.
- Unique (inserted) blocks reside between two matching blocks and are shown in blue. The corresponding matching blocks in the other file reside side by side.
- Differing (replaced) blocks are shown in red. Differing blocks reside between matching blocks, and the other file also has some data between the corresponding matching blocks.
Left-click a file in the map to jump to the corresponding position. Right-clicking displays the comparision map menu.
You can change the assigned colors by using the Tools / Layout and Colors command.
