[Zope] Upload a file to the file system

Hi, I'm brain dead for a (perhaps) trivial problem for you. I'm trying to upload a file to the file system (using an external method). I got a : <form action="uploadfs" method="post" enctype="multipart/form-data"> ... <input type="file" name="file"> ... <input type="submit" value=" Upload "></form> But I dunno how to handle this from "uploadfs" external method. Any clue ? Thanks in advance. --Gilles
