Bulk Export gives a file bulk.csv
with various attachment files (e.g. image files).
Files bulk-something.csv
are generated
by picking some kinds of data from bulk.csv
.
Files something.zip
consist of
bulk-something.csv
and related attachment files.
Files bulk-something.csv
are in character encoding UTF-8
with line ending characters CRLF
.
The database has a flexibility to store numerical/text values and attached files for user-defined parameters,
which are output into User-Defined Parameter column group
