Re: [Zope] Opening a ZOPE file object ?

Is there a ZOPE function returning a standard file handler ? (Could not find one in the API docu, but this may be because I am new.)

Not that I know of, no.

(Ideally, I would like users to be able to upload files, have them processed and download them again. This seems to be possible with LocalFS, but is it possible from within ZOPE?)

Yes, sure, but you fiddle the data directly, and not as a file. If you avsolutely need to make it behave lik a file you can put the stored data in a stringbuffer, or something like that.
