Adware! Installs 4 additional apps
tonic2August 12, 2014
Pros
Nil. Didn't bother as I don't trust it
Cons
Installs 4 additional applications, some to startup and some as browser plugins. (Enterprise 1.1, SaveSense, KNCTR, Reimage Repair).
Summary
Adware. How rude :(
Functional and fast

Pros
It's free and open source. It has plugin support. With the xdocdiff plugin you can quickly compare MS Word and Excel documents (.doc, .docx, .xls, .xlsx) as plain text. Integrates well with Tortoise CVS/SVN. Excellent performance.
Cons
Plugins are disabled by default. xdocdiff plugin is a separate download. UI is a bit dated. No support for 3-way compare/merge operations.
Summary
An invaluable tool once you have it set up the way you want it. Take a look at KDiff3 if you need to do 3-way merges.
awesome, reliable, better than my IDE

Pros
This tool provides a FAST, easy-to-use, friendly interface for diffing files. Additionally, it has never failed me. It has never crashed and/or corrupted my files.
Cons
There are none that come to mind.
Summary
Highly recommend this tool anytime you need a GUI diff tool.
Love! This software is a gem!

Pros
If you have to compare text files you reached the realm. Easy to use. Nice visuals.
Cons
Why do I need to enter 10 chars minimum of cons if there aren't any?
Summary
A well designed tool.
Performs as promised, easy to use, very fast

Summary
Highly recommended.
This tool is a must have if you develop websites
coachgm41November 19, 2010
Pros
I have to deal with 100s of files for the websites I build and this utility is one of my most important. The keyboard commands make this better than most merge utilities.
Cons
Nothing. I love this software. And its free! Its a crime. I would pay good money for this tool.
Summary
A friend showed me this tool a few years ago and I owe him big. It has saved my tail so many times I can't say. I certainly like the diff tool that comes with SVN but every time I use it I say "dang I need to take two minutes to config SVN to use winmerge instead!". I love this tool!
Wonderful, fantastic, helpful, nice, ..... etc

jamie_stephensonSeptember 7, 2010
Pros
Gives lots of control - you can move all or some changes in either direction
Cons
Filters are a bit fiddly to set up. (Hopefully someone has already done the ground work for you)
Summary
Fantastic!

Great for comparing two files that are similar. Perfect for CSS style sheets that have slight differences and are messing up your site.

None. More than I expected.
