[Zope] Export file to localmachine

Hi, I suppose, I have a newbie problem, I want to export file from zope file system, to local machine, for example I have directory with 50 text files, and I want in some programmatic way export all this files to the local machine (e.g. after press the button on the dtml-mehod), maybe someone know how can I do it? thank for help, regards Adam
