Use this attribute to determine whether this item is an actual zip entry
or is one synthesized for part of a real entry’s path. A synthesized
entry represents a directory within the zip file which has no
corresponding entry within the zip file. For example, the entry for the
directory foo/ in a zip containing exactly one entry for foo/bar.txt
is synthetic. If the zip file contains an actual entry for a directory,
this attribute will be false for the nsIZipEntry for that directory.
It is impossible for a file to be synthetic.
