[Zope] upload files from forms

[linuxcraft@scorpio.redspice.com]

Anybody tried using the form wiht file input type. Zope uses this
to upload html files from user's disk. Question is how does it 
access the file in the form variables. I cannot see anything in the
request
that shows a file. When I access the file variable all I can see is a
file name 
that the user entered. Any ideas ?

Thanks
