Ça se passe dans FormData.get_all_file_data:

    def get_all_file_data(self, with_history=False):
        from wcs.wf.form import WorkflowFormEvolutionPart
        from wcs.workflows import ContentSnapshotPart

        def check_field_data(field_data):
            if misc.is_upload(field_data):
                yield field_data
            elif isinstance(field_data, dict) and isinstance(field_data.get('data'), list):
                for subfield_rowdata in field_data.get('data'):
                    if isinstance(subfield_rowdata, dict):
                        for block_field_data in subfield_rowdata.values():
                            if misc.is_upload(block_field_data):
                                yield block_field_data

        for field_data in itertools.chain((self.data or {}).values(), (self.workflow_data or {}).values()):
            yield from check_field_data(field_data)
        for part in self.iter_evolution_parts():
            if misc.is_attachment(part):
                yield part
            elif isinstance(part, WorkflowFormEvolutionPart):
                for field_data in (part.data or {}).values():
                    if misc.is_upload(field_data):
                        yield field_data
            elif isinstance(part, ContentSnapshotPart):
                # look into old and new values (belt and suspenders)
                for field_data in list((part.old_data or {}).values()) + list((part.new_data or {}).values()):
                    yield from check_field_data(field_data)

On devrait appliquer le même traitement aux données dans part.data que pour formdata.data, utiliser check_field_data(), ça prendrait en compte le cas des blocs.
