Unbeatable. Simply the best diff tool out there.

This will be an honest review with pros and cons that will help you to purchase this software according to your need. I've been using this since more than 2 years - it's one of those programs that's incredibly powerful but takes some getting used to. When you need to compare two versions of a document or code files, this thing is brilliant. It spots differences down to a single character, shows them in a clean side-by-side view, and even helps merge changes properly. I work with a lot of text files and code, and it's saved me hours of manual checking. The folder comparison is lightning fast too - you can scan through hundreds of files in seconds to see what's changed. But here's the thing - the interface looks like it hasn't been updated in 15 years. All those tiny icons and menus take time to learn, and I still sometimes click the wrong button. There's no fancy modern design here - it's all business, which is good for performance but not so great if you're used to sleek new apps. The first few times I used it, I had to keep the manual open because some features aren't obvious at all. It's strictly for Windows too - no proper mobile version, and while there is a Linux version, it's not as polished. The price is another thing - it's not cheap, especially when there are free alternatives available. But honestly, none of those free options work as thoroughly as this one when you really need precise comparisons. What surprised me is how customizable it is once you dig into the settings. You can tweak almost everything - colors, comparison rules, even keyboard shortcuts. But again, setting this up isn't straightforward. The scripting features are powerful for automation, but only if you're willing to put in the time to learn them. At the end of the day, this is a specialist tool. If you occasionally need to compare files, it might be overkill. But if you regularly work with documents, code, or need to sync folders accurately, it's worth the learning curve. Just don't expect it to hold your hand - it's more like a grumpy expert that gets the job done perfectly once you figure out how to work with it.

Didn't find anything better.

One of the very best, most powerful file/folder synchronization applications around.

I am using this software on both Windows and Linux for over 10 years now and I can't do without it. I think that every serious programmer should have at least this software in their toolset. The price of 30 USD (standard) or 60 USD (professional) per license is a very good investment. No returning license costs either.

And above all, it's very reliable software.
