Would also be thrown if the file _is_ a ZIP file but there was some
(potentially significant) error opening it. Could consider checking
the file header for the magic sequence {0x50, 0x4b, 0x03, 0x04} and
rethrowing the exception. (Have observed {0x50, 0x4b, 0x05, 0x06} in
empty archives as well, so maybe just check for {0x50, 0x4b} i.e.
"PK".)
