We need a list with the best 3 "Folder Comparison" Windows Tools.
You need to provide why you select those 3 to be the best ones.
You need to provide the Pros and Cons of each.
You need to provide a comparison table between the top 3 showing the common and different features.
The first to submit the best results will be rewarded the project. And he/she will have the chance for more similar research work.
This should be an easy job for the right candidate.
