Well, as much as I understood, ditto should be aware of that. It is clearly explain in the man doc.
Inside the zip, it creates a special folder __MACOSX/ where all specifics extended flags are stored
You can see that doing an unzip -l

From tiger, to Leopard and Snow leopad they have change few default options....
but it's globally all the same.

What is strange, is doing a ls -la@ and ls -laO after unzipping, the "quarantine" flag is here,
but not seen at the end of the process ?

Sounds a bug to me, or I miss something.

Doing a compress folder from the contextual menu gives the same results.

Hidden flags are propagated, but not the uchg ?
