Comparison panes

One of the main differences of Visual Сomparer from other similar programs is its full-function text editor. You can copy, delete, find and replace the text in Visual Сomparer as you did it in any other text editor. All these possibilities are realized in comparison panes. Each pane represents the content of one file being compared, allowing its edition and merging of different blocks with the other file.

Comparison Map and quick navigation

Comparison Map and quick navigation For convenient moving and full scope of file differences Comparison Map is intended. It consists from area of differences and scrollbar. Using Comparison Map, you can move quickly through the differences. You can do it both with help of scrollbar and direct cursor positioning.
