Using NIO2 for writing zip file entries without corresponding folder entries

[Rafael Winterhalter]

Yes, this would be an option and I understand that this is a corner-case
but if it can be covered, great. Ideally, one could also choose to have
only certain directories stripped for allowing to retain as much as
possible of the original format.
Thanks for considering this!
Best regards, Rafael
