Colors and symbols

Plugin Compare uses different colors and icons to indicate changes in your file. You may have added, deleted, moved or changed the line.

1. Added - Added (+): The line exists only in the new file, not in the old file. The color used for highlighting is green.
2. Removed - The line does not exist in the new file and is only present in the old file. The color used to highlight is red.
3. Moved - Moved : The stream appears once in another file and in another location.
4. Changed - Changed : Most lines are identical in both files. You will see the changes highlighted in orange.
