Single- and multiple-character wildcards still function as
    expected with ODS-5 files. A single-character wildcard represents
    exactly one character in either the file name or file type, but
    may not be used in the file version string. A multiple-character
    wildcard can represent any number of characters starting with
    zero in the file name or file type. A multiple-character wildcard
    can be used in place of a version string.
