This window has two halves, with the first file appearing in the left pane and the second in the right. The window initially opens with the first point of difference appearing at the top. The name of each file appears at the top of its respective pane. Two scroll bars appear, one at the right of each pane. In the two views, a red entry indicates a deleted line, a blue entry indicates a changed or updated line, and a green entry indicates an added line.
Black lines are unchanged between the two panes.
To see only differences, click on the Difference Only button. To display line numbers, click, click on the Show Line Number button. After viewing the contents of the window, click OK to close the window. Refresh Executes the previous search command, without prompting the user. Label Menu Labels are a conceptual way of grouping files.
