Deltopia DeltaWalker from Deltopia Inc. (http://www.deltopia.com/) is object of our today’s review. Rather large distributive for such programs (15 Mb) and very observable consumption of RAM (100 Mb and more) camouflage a program with rich functionality, handy and nice interface.

Welcome screen can help you with main important things for starting work with this product: you can read short overview about DeltaWalker, read “Tips & Tricks” that might help you make easier communication with program, read about purchasing full version (Delltopia offer 30-day fully functional license) and of course main functions of the program: “Compare Files” and “Compare Folders”.

Interface very friendly and unobtrusive. Most of elements can be changed, added or removed from the main window.
By default main window has two panels for file comparison where you can choose required files.

There are several ways to open files:
• You can as usually find and open files as in windows explorer;
• You can drag and fop them to program’s window;
• And you can copy content of files and paste it to built-in editors in each panel. It very interesting and comfortable method.

After comparison you can see all differences between two files. To be more visually all similar blocks in files are connected and marked different colors: deleted text blocks, added text blocks and different text blocks.
You can do all operations with files after comparison such as: replace matching difference with this difference, add this difference after matching difference and delete this difference. So you can easily modify either initial or result file.

Two files also can be merged after comparison with so called “thee-way comparison”. It means that two compared files will be analyzed and merged to one result files with respect to a mutually common file referred to initial files.
Folder comparison has similar functionality so there’s nothing important to add.

File and folder comparison can be done in the same time in main window and it’s useful as we can do these operations together.

Deltopia DeltaWalker is multi-platform product: Windows, Unix and Mac are supported. It’s very unusual for such kind of products.

In summary we have very friendly and powerful product that can be used most of the users from different computer platforms because of multi-platform orientation with rather low price ($29.99 per personal license).
