Compare++ also called CMPP, is a visual diff tool which can do source code, file and folder comparison and synchronization with terrific speed. Based on thorough understanding of source code structures, Compare++ makes reviewing and merging simpler and more intuitive. And also, it visually lists all changes of structure such as function, class in a dockable pane "Function View". With this feature, code review or refactoring will be more comfortable for programmers.

What you can do with Compare++
1. Do file, source code or folders/directory comparison
2. Review code structure changes
3. Compare sub-sections of files
4. Visually display comparison results in side-by-side or over-and-under mode
5. Browse combined file comparison results
6. Merge one or more difference from one side to the other
7. Compare or open the containing folder for loaded files
8. In-place editing and comparing files

For comparing files,
1. Use structured comparison engine
2. Provide two modes( "Code-oriented" and "Text-oriented" ) to make comparison more efficient and effective
3. Deep understanding of syntax and code structures such as C++ functions, classes...
4. Visually show all code structure comparison results(changed,removed,added) in Function View
5. Easy to merge multiple code structure changes at once
6. One step to merge multiple differences
7. Support HTML and text report
8. Support browsing comparison results in combined mode
9. Align code structures, for example, align functions and even {} for C/C++ programmers, which is one of the unique features only provided by compare++
10. Very useful overview bar with three models(linear, Piecewise linear, logarithmic) to help locate differences
11. Unlimited text length in a line
12. Highlight syntax

For comparing folders,
1. Compare folders at high speed
2. Display system icons according to file type in folder comparison window
3. Easy to activate file view to look at the detailed comparison results
4. Powerful "Compare to..." makes it easy to compare any two selected files

For usability,
1. Integrates into Windows Explorer's context menu
2. Easy to integrate with other products such as version control system
3. Rich customizable shortcuts make operations easier
