I don't have a sample script, but some clues to help you on. First of 
all, learn to check and search help from the Zope Books API section 
and/or the help in your Zope server. These files give you some idea 
atleast.

And then the best source for help is the source code. If you see 
something done in the Zope interfaces etc. you can try to look for those 
sources too, for some help.

But now for the real help:

With the form - listing all the files in the directory, you can get a 
good idea from the Examples that come with Zope. There is the 
FileLibrary example that shows you a lot.

For File object, the update function is manage_edit. So in your script 
you will call this function for the object you want to update.

Below is how it is defined in the source ( lib/python/OFS/Image.py ):

def manage_edit(self, title, content_type, precondition='',
                     filedata=None, REQUEST=None):


Hope this helps.
