My purpse is When I public some documents, that documents will be copied to another folder that I want to. Could you tell me how to sold this proble.

Since you make many assumptions about what we know about what you're doing, I'll do the same, and you can correct those if I'm in error. You will want to attach a script to your workflow transition to the published state that does this. See here on how to manipulate DCWorkflow: http://www.zope.org/Members/hathawsh/DCWorkflow_docs --jcc
