Dear Thunder,
We are now in version 68.7.0, Did you already succeed in implementing this solution? I do not find it in the AttachmentExtractor Continued options.
Congratulations for the extra, it is helpful 
. But it would really be even more helpful if the link to the detached messages within the emails could be retained. This would enable seamlessly reducing the size of Thunderbird files by detaching all attachments of all messages into a folder, The size of TB files is really a big hassle in many ways. Mine is beyond 20GB!...
Thanks,
Francisco
