THIS IS IT.
Look absolutely NO further for a powerful and intuitive difference identification tool.

If you are a developer, I challenge you to try this application and find fault. Honestly. Customizable file filters, hotkeys, interface colors. This does everything you wish your current diff tool did.

But even if you aren't a developer (thats me), DeltaWalker will help you get even your casual tasks squared away: backups, photo/music library consolidation etc.

Conducting even the most basic of tasks with this software, it becomes immediately apparent that a great deal of care and effort has been put into the making thereof.

The best part? This amazingly lovely hunk-o-code is CROSS-PLATFORM! I myself have had great success using it across OSX, Ubuntu and all three Windows (XP, Vista, 7). It's just priceless to be able to switch environments and have the same, familiar tool at hand. And yes, one license entitles you to the use of DeltaWalker on any/all the above platforms.. !

And I haven't even mentioned the considerate, helpful and prompt customer service, simple registration process or easy installation..

Small price to pay for such great software, keep up the good work.
