Parameter Discussion
sourceFileName and targetFileName may contain wildcard characters ‘?’ and ‘*’. If
sourceFileName has wildcards, all matching files are copied. If targetFileName has wildcards,
it will be matched to sourceFileName. If the target file is a directory, the existing file (or group
of files) will be copied into the directory.
sourceFileName may also be the empty string (""), in which case the file found by the most
recent call to GetFirstFile or GetNextFile is copied.
