# S3 File Output

The S3 File Output step writes data as a text file to [Amazon Simple Storage Service (S3)](https://docs.aws.amazon.com/AmazonS3/latest/dev/Welcome.html), a cloud-based storage system.

**Note:** [Using the Text File Output step on the Spark engine](https://github.com/pentaho/documentation/blob/main/PDIA/9.3/PDI/Transformation%20steps/PDI%20transformation%20steps%20reference%20\(overview\)/Text%20File%20Output%20cp/Select%20an%20engine%20\(Text%20File%20Output\)/Using%20Text%20File%20Output%20on%20Spark%20engine%20cp=GUID-A690584E-301A-4294-8EA0-C1B693E6DD70=2=en=.md) is recommended for writing data to Amazon S3 when you are using Spark as your [Adaptive Execution Layer](/pdia-data-integration/9.3-data-integration/advanced-topics-pentaho-data-integration-overview/adaptive-execution-layer-cp-landing-page.md).
