Thanks for you reply.  

My situation is I want to synchronize my files from my local driver C:
to a network driver \\Wua141699 in Windows. The network drive is not
very stable and I need use my copy program to copy and verify files
instead unison's native copy method.

Can I make this happen? I have tried hard but I can not finish it.
