/CREATED (default)

    Modifies the time value specified with the /BEFORE or /SINCE
    qualifier. The /CREATED qualifier selects files based on their
    dates of creation. This qualifier is incompatible with the other
    qualifiers that allow you to select files according to time
    attributes: /BACKUP, /EXPIRED, and /MODIFIED. If you specify
    none of these four time qualifiers, the default is /CREATED.
