Diff Commander is a powerful tool to compare and synchronize all directories you want in a simple and efficient way.
This software allows you to compare two different directories and find their differences; these directories may be in the hard disk or in different PCs connected on a Net.
Once those differences are found you may administer them as you want; you may edit, copy and modify. Those files; you may also eliminate them from a directory or form another from both at the same time.
