The results of a comparison display as a split-pane and connecting splines for identifying where the deletions, changes and additions occur. Each file in a comparison takes up half of the comparison results window. At the top right-side of the window, view the total number of differences discovered. Comparisons show the character differences in a modified line with bolding and background color highlights indicate modified blocks. If the files are not identical, the differences are highlighted by default in pink (deleted), purple (changed) or green (added). You can change the colors for the difference highlighting from the Options dialog.

Do not ignore: Performs a case-sensitive comparison and does not trim occurrence of whitespaces and empty lines. Ignore case: Performs a case insensitive comparison. Trim whitespaces: Trims the trailing and leading whitespaces. Trim whitespaces and ignore case: Trims the trailing and leading whitespaces and performs a case-insensitive comparison.
