    Variable WARNING_MISSING_ZIP64_EXTRA_FIELDConst

    WARNING_MISSING_ZIP64_EXTRA_FIELD: string

    Warning reason: a central directory record holds the Zip64 sentinel in a size, offset or disk number field but carries no Zip64 extra field resolving it (see ZipReader#warnings). The entry is listed, its sizes and offset are unusable, and reading its data or copying it with ZipWriter#appendZip throws ERR_EXTRAFIELD_ZIP64_NOT_FOUND; the other entries are unaffected. Under strictness: "strict", ZipReader#getEntries throws ERR_EXTRAFIELD_ZIP64_NOT_FOUND instead.
