By default, AccuRev diffs files using its own Diff Tool. You can also configure AccuRev to use third-party diffing tools. Results from file diffing operations (Diff Against Backed or Diff Against Basis, for example) are always displayed in the Diff tab:
The Diff tab shows the files being compared side by side in realizable panes. The older version is displayed in the left pane, the more recent version is displayed in the right pane. The differences between the files are color-coded:
The navigation map, to the right of the vertical scroll bar, shows the relative locations and sizes of the areas that differ between the two files. It uses the same color-coding as the difference sections. Click on any point within the navigation map to scroll directly to that area in the file.
