I just used this code to upload the file, but the file is uploaded in 
the Zope file system. If I want to use my python program for the 
encoding (or my python external method) , the file must be in my 
computer file system out of Zope right ?

Can't follow you on this one clearly... I think if I can accomplish the 
previous tasks I should be able to do something with that.
