Here's something that worked for me, it's got extraneous imports and 
stuff ('cos it's the front end of something bigger), but it does 
work. I add nnn_ to the beginning of file names so I can have more 
than one file called 'test.doc' in the directory, and I've not 
finished the URL stuff yet, but it certainly uploads normal files to 
LocalFS (probably because it bypasses the LocalFS machinery all 
together ? :) .

add_details is a ZSQL method that adds info about the upload into a database.

savedir = "/home/zope/UPLOAD_FILES"

thefilename = split[-1]

     if url:
         oname = os.path.join(savedir, "%s_" % nxtfile)
         f = open(oname, "wb")
         f.write(url)
         f.close()
         content_type = 'url'
         filesize=os.stat(oname)[6]
         thefilename = url
         okay = 1
         results = "Got a URL [%s]" % url
else:
     file.seek(0)
     oname = os.path.join(savedir, "%s_" % nxtfile + thefilename)
     f = open(oname, "wb")
     body=file.read()
     f.write(body)
     f.close()
     content_type, enc = guess_content_type(oname, body, None)
     filesize=os.stat(oname)[6]
     okay = 1
     results = "File saved %s, size (bytes) %s" % (thefilename, filesize)

if okay:
 
self.add_details(nxtfile=nxtfile,filename=thefilename,filesize=filesiz 
e,content_type=content_type)
else:
     results = "No file was specified"

template_str = self.index_html.read_raw()
template = DocumentTemplate.HTML(template_str)
theresult = template(self, results=results)
return theresult

It's not quite production quality (need to fix the URL stuff), but it 
works nicely with LocalFS.
