Serial number (000 to 999) that is appended when
a single file exceeds 2 GB
Regardless of whether the auto naming feature is set to OFF, Numbering, or Date, if the data
size of a single file exceeds 2 GB, an underscore and a three-digit sequence number (000 to
999) is appended to the file name. The sequence number is incremented by one each time a
file is added. This is appended only if the file exceeds 2 GB.
