OnSetExtraData will be a callback to collect data to be stored in the
'extra' field.
At the moment it is possible to read that data (raw) from the 'contents' but
there is no way to write it (I suppose then I will need to make another
function to alter it).
I will probably write it raw and limit it's length to 512 bytes.
I can possibly make changes to save changed/added files for a zip file but
only to modified name ie zipname.NEW.zip.
