Hi,
Thank you for your choosing SyncToy. It's really a good tool for your daily synchronizing.
I'm afraid you should clear one thing about SyncToy: SyncToy is not a tool to make your LeftFolder equal to your RightFolder, but a tool to reflect the changes from LeftFolder to LeftFolder. So, actually speaking, if you want to make SyncToy synchronize deleted and renamed files, you should delete or rename these files before the first syncing by SyncToy.
I hope this can be a illumination of your question.
Thanks,
Danish
