After reading all suggestions I decided to try first the defaultdict(list), as first suggested by Oscar, in several steps. First with sizes and then with other partial contents or/and "strong" hashes as suggested by Cem. Thank you very much to all who responded for all helpful suggestions. If I find something better I'll report here. Paulo -- https://mail.python.org/mailman/listinfo/python-list
