First, create a proper [import](/system/ergonode-transfer/import.md) or [export ](/system/ergonode-transfer.md)profile. Depending on the case, you may need one or more import files checked.

Download the custom\_fields\_et\_import\_example.zip and take a look at the files included inside it.&#x20;

{% file src="/files/4XODvEUMfD8ZEz48z9sx" %}

ZIP file includes [attributes.csv](https://docs.ergonode.com/ergonode-transfer/overview/files-format/attributes.csv) , [custom\_fields.csv](https://docs.ergonode.com/ergonode-transfer/overview/files-format/custom_fields.csv) , [multimedia.csv](https://docs.ergonode.com/ergonode-transfer/overview/files-format/multimedia.csv) , and [options.csv](https://docs.ergonode.com/ergonode-transfer/overview/files-format/options.csv) files, which are necessary to import and create everything that is needed to use custom fields.
