I thought that the Sync was now supposed to do a true "mirror", but that does not appear to be the case. In my tests, Sync will propagate deletions, but only files that were previously synced, not files that were on the Destination beforehand. Meaning, I have 2 folders, Test1 and Test2, any files added or removed to Test1 are synced to Test2, including Deletions, but files added to Test2 are not removed, even if they do exist in Test1.
Is there no way to do this? I can do it with "robocopy /MIR", so I guess I'll have to go back to using that, but would be nice to be able to say, "make Test2 just like Test1".
