# Sync file uploads to Amazon S3

> Upload file submissions automatically to an Amazon S3 bucket with your Fillout form. Optionally set a dynamic file path to categorize submissions into nested buckets.

## What is Amazon S3?

<Info>
  The Amazon S3 integration is available on the **Team** and **Enterprise** plans. Learn more about the [Team plan](/team-plan).
</Info>

[Amazon S3](https://aws.amazon.com/s3/) (Simple Storage Service) is a scalable cloud storage solution provided by AWS, designed to store and retrieve any amount of data with high availability and security. Ideal for businesses and developers, S3 offers cost-effective, reliable data storage for applications, backups, and content distribution, making it a top choice for cloud storage needs.

## How it works

<Steps>
  <Step title="Link your Fillout form to Amazon S3">
    Click `Integrate` on top followed by `Amazon S3`. If you don’t already have an access key to AWS, you can create one under **Security Credentials**. More details [here](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_access-keys.html#Using_CreateAccessKey).
