Home > Software > Duplicate Commander 3.2.5448

Version 3.0 has multiple known issues, crashes, bugs, etc. The current beta version has progressed a lot since the last stable released over 2 years ago, and I've gotten nothing but positive feedback from it. It is highly recommended that you use the current beta.
