Unfortunately this tool does not appear to do anything at all. There does not appear to be any documentation.
I tried the suggestions found in other reviews. Regardless, it always immediately says no duplicates found, before it has time to search, and I know that is not correct.
Very disappointing as I need a tool to remove duplicates.
Please let me know when there is documentation available and the tool works.
If and when it does work, I would like to donate for it.
