I use Mirror and it simply outputs:
Starting... Finished...
However, I know the folders aren't the same. Even if they were, Toucan should still do something, otherwise I'd use Update.
Also, checking the Preview box overrides the Function set. i.e. If I set it to Update and tick Preview, it will use Copy instead.
One last problem. When updating, if you click Abort, it will display an error saying that it couldn't read or write the file times of the files that it didn't get up to.
Sorry for pointing out your faults, Steve
