# Loading a column of the VARBYTE data type
<a name="copy-usage-varbyte"></a>

You can load data from a file in CSV, Parquet, and ORC format. For CSV, the data is loaded from a file in hexadecimal representation of the VARBYTE data. You can't load VARBYTE data with the `FIXEDWIDTH` option. The `ADDQUOTES` or `REMOVEQUOTES` option of COPY is not supported. A VARBYTE column can't be used as a partition column.
