Other than the comment at end mail this will be my last message, I
cannot add anything else to this discussion, you and the kde developer
have all the elements needed to make a choice.

most kio need to be modified (and indeed it would be good also for other

it's  not -a
it's -X for rsync
it's --xattrs for tar (no short option)
it's not supported by zip (who care?)

it's a mess
And windows?
