Binary files in KNIME are saved in a table format, which includes column headers and RowIDs from the original data table and other possible settings about encoding, commas, and quotation marks.
.table is a KNIME proprietary format. This means that on one side the final file is optimized for speed and size and the reader node needs no settings about the file structure, but on the other side it might not be portable to other platforms.
Reference workflow is available in the EXAMPLES server under:
