How to: Configuring File Adapters
Parse Server allows developers to choose from several options when hosting files:

- `GridFSBucketAdapter` - which is backed by MongoDB
- `S3Adapter` - which is backed by [Amazon S3](https://aws.amazon.com/s3/)
- `GCSAdapter` - which is backed by [Google Cloud Storage](https://cloud.google.com/storage/)
- `FSAdapter` - local file storage

`GridFSBucketAdapter` is used by default and requires no setup, but if you're interested in using Amazon S3, Google Cloud Storage, or local file storage, additional configuration information is available in the [Parse Server guide](http://docs.parseplatform.org/parse-server/guide/#configuring-file-adapters).
