# Writing Data to Amazon S3
> Export data from MotherDuck to Amazon S3 or transform S3 files in place.
You can use MotherDuck to transform files on Amazon S3 or export data from MotherDuck to Amazon S3.

:::note
MotherDuck supports several cloud storage providers, including [Azure](/integrations/cloud-storage/azure-blob-storage.mdx), [Google Cloud](/integrations/cloud-storage/google-cloud-storage.mdx) and [Cloudflare R2](/integrations/cloud-storage/cloudflare-r2).
:::

MotherDuck supports the [DuckDB dialect](https://duckdb.org/docs/guides/import/s3_export) to write data to Amazon S3. The examples here write data in Parquet format, for more options refer to the [documentation for DuckDB's COPY command](https://duckdb.org/docs/stable/sql/statements/copy.html).

## Syntax

```sql
COPY <table name> TO 's3://<bucket>/[<path>]/<file name>';
```

## Example usage

```sql
-- write entire ducks_table table to parquet file in S3
COPY ducks_table to 's3://ducks_bucket/ducks.parquet';

-- writing the output of a query will also work
COPY (SELECT * FROM ducks_table LIMIT 100) to 's3://ducks_bucket/ducks_head.parquet';
```
