[Zope] ExtFile Product and mime-types

[Marc Roland]

After importing a new file via PythonScript
manage_addProduct['ExtFile'].manage_addExtFile(id, title, descr, file)
some files have automatically the Content-Type
'application/octet-stream'.

How do I change the identification of these files afterwards, and
how can I change the Product's autodetection for the next files to
upload?

I use ExtFile Version 1.1.3.
