Altova DiffDog it’s a powerful product from http://www.altova.com/ that allows you make comparison between files and directories, merge required content and create report so it will be much helpful to demonstrate differences visually.

You have many unsorted notes or documents those changes and you have no time to check and merge them manually? Or maybe you have huge heap of photos or any other files in several directories and you have no time to check duplicates and arrange it? Many similar files can not only leave litter your hard disk but also your brain when you trying to find the latest version of very important document in this chaos of files.

DiffDog will be reliable assistant and can help you in such case.

Interface of the program is friendly so in most cases can be used without help system.

In main window you can see all required buttons and menus that will help you in any task you need.

At first you could choose what do you need to compare – files or directories?

Directory comparison allows you to check files into two chosen directories.

Quick comparison mode – it will be activated automatically when two directories with files are chosen. This mode compare file size and date of modification only.

If any file is missing in one directory but present in another you can use “Synchronize” option and content of the directories will be equal.

From directory comparison you can run file comparison for required files. There are several modes you can choose:

• Text comparison mode – make comparison between files as text files.

• XML comparison mode – make comparison between files as XML files.

• Binary comparison mode - make comparison between files as binary files.

• Extensions comparison – make comparison between files as text, XML or binary depends on their extension. You can choose and set extensions in options of the program.

After comparison is done you can export all changes and make a report. It rather helpful if you need to find out only differences without checking the entire document.

DiffDog has more features that can be used for absolutely different needs, so it’s very hard to describe them all.
