Downloaded and gave it a try today.
I used it to sling a group of files consisting of a dozen+ huge ISOs over to an archive drive. It performed very well. Didn't even hiccup on the two 4Gb monsters in the collection. For uses like this, having a built-in error log is worth its weight in gold. Sweet!
Not quite as fast as Unstoppable Copier, but it's a much more sophisticated app so that's to be expected.
Thanks for bringing it to my attention.
