I am trying 1.3 Beta on Vista and it is working. One comment though (or maybe a wish) I was hoping that the Master folder could be chosen in the Search phase. In other words, have a master folder identified and then see if there are any other folders which have a duplicate of a file in the master folder. At present, all duplicates in all of the paths are identified...but there is no guarantee that there is a duplicate in the master folder, only that files will not be deleted in the master folder. Hope this makes sense (and that I have understood the program).
Thanks again for a good utility.
