Genealogy sites MyHeritage.com and Ancestry.com as well as genealogy programs like RootsMagic, Legacy Family Tree, AncestralQuest, Family Historian, and many others are great for presenting family trees, displaying your data in a straightforward graphical form. However, one Windows program allows you to really understand your tree, to spot problems, links, and patterns you might have missed.
FTAnalyzer is an open source tool for Windows which imports your data in the form of a GEDCOM file, then analyzes it by using a number of useful reports, providing details you might not have uncovered any other way.
