Hi Alex, I just use a simple external method for this purpose.  I have a
form that has a file input box called "file".  The form posts to this
external method using method="post" and enctype="multipart/form-data".

It's a small function, so I'll just post the code here:

def processFile(self, file, REQUEST=None, RESPONSE=None):

    buffer = file.readlines()

    outfile = open('%s/new_data.txt' % ATTACHMENTS_HOME, 'w')
    outfile.writelines(buffer)

    if REQUEST is not None:
        return RESPONSE.redirect('%s/updated.html' % REQUEST['URL1'])

ATTACHMENTS_HOME is a variable I define elsewhere in the module.  After
the file is saved, I just have it redirect to a page called
updated.html.

There's normally some processing that goes on between the readlines()
and the writelines(), but I cut all that out so you could see the
basics.
