It's based on Column Tree control. z_zip_diff_demo2 shows the old ZIP-like file (white page) compared to the new ZIP-like file (envelope), the old file contains "deleted.txt", "changed.txt" and "unchanged.txt", the new file contains "added.txt", "changed.txt" and "unchanged.txt", the contents of "changed.txt" is different between the two ZIP-like files, but not the one of "unchanged.txt":

  

  • unchanged/No color: file exists in both ZIP-like files and its content is identical
  • deleted/Red color: file exists in the old ZIP-like file only
  • changed/Yellow color: file exists in both ZIP-like files but its content is different
  • added/Green color: file exists in the new ZIP-like file only
