[Zope] Does Zope's FTP server provide "resume after disconnect"?

Hello, I'm trying to setup a CMF site. This will hold large (~50MB) binary files too. I'm thinking of using CMFOptions for ExternalFile support so that this won't fill up ZODB. Question: People might want to download files via FTP. Does Zope's inbuilt FTP server provide functionality where broken downloads can be resumed? Thanks in advance Satheesh Babu http://vsbabu.org
