I try to install LocalFS with no success ( Zope never include it in the 
product list).
Using ExtFile I just could have access to my file systems, how can I use 
it to upload a file from my website visitors pc ?

Already reading , thank's.

That's a solution but do you know something more GUI like a progress bar ?

My python program change the original file, it doesn't create another 
one after the encoding. Can I use the same Zope object or it doesn't 
work that way ?
