Yes. It looks it uses
from OFS.content_types import guess_content_type
which in turn uses Python mime_types module
which defines 120 or so mimetype2ext mappings.

I'm just one of those guys who prefers explicit from implicit :-)

Yeah, mimetypes seems to look for mime types in:
     "/etc/mime.types",
     "/usr/local/etc/httpd/conf/mime.types",
     "/usr/local/lib/netscape/mime.types",
     "/usr/local/etc/httpd/conf/mime.types",     # Apache 1.2
     "/usr/local/etc/mime.types",                # Apache 1.3

and there's also a mime.types in OFS.

Even though, in a Product I would rather not require the user to
configure mime.types just to install my prodct :-)
